In what is perhaps yet another signal of end times upon us, an asteroid that is the "size of London's Big Ben clock tower" is going to fly past the Earth tonight, moments after the end of the next Presidential debate.

It'll pass the Earth safely on Thursday at 10:49PM EST, Fox News reports.

The asteroid is called 2020 TGI and is traveling at an estimated 30,700 miles per hour. It's going to miss the Earth by about 7 million miles.

It had recently come close to the Earth on April 20, 2013 and won't make its way back around again until Feburary 6, 2024. It is estimated that the asteroid is between 154 and 360 feet wide. "Potentially hazardous" near Earth objects are defined as those who come within 0.05 astronomical and measure over 460 feet in diameter.

There's currently more than 18,000 of these near Earth objects.

One asteroid "the size of a pickup truck" passed the Earth by just 2,000 miles in August. It was the closest call ever recorded and NASA didn't notice the object until after it had passed the Earth. In 2018, the agency put together a plan for the Earth to better prepare itself against near Earth objects.

NASA Administrator Jim Bridenstine said in 2019 that an asteroid strike was the possibly the planet's biggest threat. The topic of asteroids and other existential threats, including volcanos, pandemics and earthquakes, was also discussed last week on a podcast with University of South Florida professor Dr. Marc J. Defant.

But with the way the year has been going, we're sure there's plenty of people out there with their fingers crossed that the asteroid will change paths and finally put an end to it all...

Press review: NATO on guard over space threats and the rubleâs direction after US election

NATO Secretary-General Jens Stoltenberg said on Wednesday that competition in space is rising every year and claimed that Russia and China are developing anti-satellite systems, which could "blind, disable or shoot down satellites and create dangerous debris in orbit." According to Dmitry Stefanovich, research fellow at the Center for International Security at the Institute of World Economy and International Relations, the focus on "space threats coming from Russia and China" was expected. “This has become the universal rationale for any activity in the field of military development of NATO countries,” he told the newspaper. The commentator believes that at the first stage a more advanced system for space monitoring will be created, "which is not bad for mankind." "Moreover, in the event of some normalization of NATO-Russia relations, a kind of a "single window" for cooperation could emerge, for example, with our system for space control." Earlier, Russia put forward initiatives on creating a single catalogue of space objects, he recalled.

On the other hand, according to German media reports, the new center could further coordinate "space defense." "This is just a step away from a ‘space attack'," the expert warned. So far, space has not become a battleground, but space infrastructure is a key element of ensuring combat actions on the planet’s surface.

Russia and China have accused the US and NATO of seeking to turn outer space into a new battleground. At the UN, Moscow and Beijing are promoting the idea of signing a legally binding agreement on banning space militarization. However, the countries fail to agree on universal rules of behavior in this field.

More and more will appear soon. To everyone: If you are interested, you can observe the sky wherever you are and notice the red/purple explicit coating, in the evening. This is comet's dust, and this is something that wasn't observable in the previous years. For good observation, you will rather need to wait for the evening or morning and observe areas of the sky near the horizon; however, I see it even at the day, however near the horizon, but yet. It will arise systematically, geometrically.

I am not sure if this meets your criteria Luks but the sky does look dirty at the horizons as you said.
The cabin view is dated ‎Friday, ‎August ‎17, ‎2018, ‏‎07:44:26 AM-on French territory. I'll keep watching.

It could be, but this is hard to tell what I exactly see in these pictures. You have to decide for yourself.

I can only trust my own eye and sky that I know very well. I observe through years of these spaces of the sky visible to me through the day and night (rather evening), I am sure that it is changing.

Just do it yourself, particularly those who have a good view of the sky in the evening, check the horizon and check the clouds.

You will notice the changes by yourself. I guarantee.

BTW: All those things as the "Virus" and probably soon "State of War"/"Third World War" (that can be soon introduced; based on the proxy conflicts between superpowers and as the replacement or even enhancement for the lockdown which people are already less and less able to tolerate) are for three things:
1) More control over people and everything that they do.
2) As more as possible, create damage to society in the areas that the PTB will not use directly (scorched earth policy).
3) Divert attention from the Earth and Cosmic Changes.

And the third point is one the most important. I think this is why on the TV we see "virus", "virus", "virus", around.

I agree! It's not quite there but your insight with the “event horizon” is where it might be witnessed first, perhaps.

Jesus. Poor pilots in the masks. Such the responsible roles they have and commanded to wear the masks that can risk hypoxia and the loss of consciousness and the crash of the whole plane... How to call them otherwise as not the psychopaths - all those who impose wearing masks on others...

But coming to the main subject... Yeah... When you look at the newest photos or videos, you can see that colors are different. This is one thing that can be observable.

However, as I said, many things can be observable just by our own eyes, without any specialistic equipment or viewpoint. Almost in every place in the world, changes in the sky can be visible.

I encourage everyone to observe the sky. You can see there a lot, I think. If you are not sure, ask another for their opinion.

I noticed that people do not think about and do not see this change in colors and dust in the sky or clouds, but where they are asked for the opinion, many people told me that, yeah, the sky is different from what they had known from the past.

A very long-path fireball ran this morning. It looks like the fireball that flowed at 2:16 on October 25, 2020 was seen with a wide-angle camera from Fuji toward the southwestern sky. It exploded on the way and left a meteor mark. You will hear a sound as soon as it glows, and after a first snap, you will hear a crumpling sound on the paper (no sound before or after)

The place of the suspected impact should be examined during the crew’s next spacewalk, Sergei Ryzhikov added
MOSCOW, October 30. /TASS/. The crack found aboard the International Space Station (ISS) and the air leak it caused could have been caused by an external impact, members of the Russian crew of the space station stated during a conference with the Mission Control center.

Speaking with Flight Director of the Russian segment of the ISS Vladimir Solovyov, Russian cosmonaut Sergei Ryzhikov said: "If you take a closer look at the picture, there are changes of color in the middle of the crack."

"We suspect an external impact," Ryzhikov said adding that the place of the suspected impact should be examined during the crew’s next spacewalk, which is scheduled for November 18.

Solovyov said that such venture may be very complicated: "You do know well that it is very difficult to reach this place during the spacewalk as there are numerous cables and you will also have to detach a thermal isolation. This is why it will be hard to reach this place from the outside."

A source told TASS in August that the space station’s Russian-American crew was working on tracing an air leak aboard the orbital outpost. Later, Russia’s State Space Corporation Roscosmos confirmed this information.

The air leak spot​

The ISS crew reported to Russia’s Flight Control Center on the morning of October 15 that the cosmonauts had found the possible air leak spot in the inter-section compartment of the Zvezda module with the help of a tea bag. As the cosmonauts said, the air was possibly leaking through a fracture. The crack was no more 4 cm wide and posed no threat to the space station’s safety, Roscosmos specified.

Cosmonaut Anatoly Ivanishin said at a post-flight press conference on Wednesday the air leak spot looked like more a curvilinear scratch 2-3 cm long.

The air leak spot has now been sealed with temporary means. Meanwhile, a source in the space industry told TASS that the air leak would be fully eliminated after the Soyuz MS-16 spacecraft’s landing. As the source explained, this measure was required to make some measurements with the closed hatches.

[Cosmos]

Now, we had an all-time record year for such objects last year (2019), as you can see here:

List/Graph "11 = All NEOs Closer than the Moon:..." in Folder "C = Close Calls nearer than Moon:...":

2019 is the record year! Also notice when it started to increase...

As you can see above, in 2019 we had 82 close encounters with such objects (the ones we didn't detect, not even mentioned here!). That means that in the year 2019 an object like that flung very close by earth on average about every 4.5 days! Now, compare this number for example with the year 1991, which was the year in which the first ever object of this kind was discovered/detected. In 1991 only 2 objects of that kind flung very close by earth. Which means that in 1991 an object like that flung by earth on average "only" about every 182.5 days. Or take a look even just at the year 2006 for comparison above; there were still "only" 6 such objects discovered/detected.

Now, how many of those 82 objects in 2019 were discovered ahead of time and how many after the close approach already happened? If you arrange/order the list accordingly, you will see:

54 Objects were discovered on the same day or too late, which gives us roughly 65.85%.
28 Objects were discovered ahead of time either one day before or earlier, which gives us roughly 34.15%.

However, out of those 28 Objects 12 Objects have been discovered just 1 day before, 4 Objects two days before, 6 Objects 3 days before, 1 Object 4 days before, 1 Object 6 days before, 1 Object 9 days before, 1 Object 10 days before, 1 Object 11 days before and finally, 1 Object 13 days before. And that's it.

So, if we are in a really generous mood and say that we could have done something to protect or prevent the earth from being hit by those Objects in 2019, that we detected a week earlier and above (7 - 13 days), then we have to say that in actuality we couldn't have done anything about the remaining 24 Objects out of those 28. Which would mean that we couldn't have done anything against 24+54 Objects out of those 82 Objects, which gives us roughly a sum of 95.12%.

But, I would dare say, that we, realistically speaking (with the capabilities at our disposal nowadays) couldn't have done even a darn thing against that object that was discovered 13 days before. So that means, sobering enough, that 100% of those 82 Objects in 2019 would have hit earth without us having the slightest chance to do anything about it, since they all, without any exception, were discovered much too late and thus that we are basically screwed against the power of the cosmos!

And in case you are wondering if 2019 was an exception in that regard or if we have been improving (detecting things well ahead of time) since 1991, I'm afraid to have to disappoint you'll with "bad news" here too. 2019 was not exception and it pretty much looks that this sobering ratio doesn't improve at all over time, in any shape, form or fashion.

Just a short update on the graph above and all the associate data: It looks like we have already (as of now) broken the above record from last year by quite a margin in 2020, and we still have two months to go for this year! And that's despite the Covid-Nonsense probably having significantly decreased the observership capabilities this year with observatories being shut down and such. I'll update all the data next year. Stay tuned!

BIG COMET ATLAS: Comet ATLAS (C/2020 M3) is approaching Earth. At closest approach on Nov. 14th it will be 0.358 AU (54 million km) away--not quite near enough to make it a naked-eye object. But can you say "photo-op"? Amateur astronomers with small telescopes will find it to be an easy target glowing like a 7th or 8th magnitude star. This preview comes from Michael Jaeger of Jauerling, Austria:

"I took the picture on Oct. 28th using my 11-inch telescope," says Jaeger.

The comet's green atmosphere is huge. This composite photo from Dan Bartlett of June Lake, California, shows that it is nearly as wide as a full Moon. Hence the following tip for astrophotographers: You'll need a wide field to capture the entire comet. It gets its verdant hue from diatomic carbon (C2), a compound which glows green in the near vacuum of space.

On the date of closest approach, Comet ATLAS will be in the constellation Orion. Exact coordinates may be found here.

Massive asteroid subject of new findings | University of Hawaiʻi System News

University of Hawaii at Manoa astronomer Dave Tholen has revealed critical new findings linked to a large asteroid expected to pass extremely close to Earth.

www.hawaii.edu

October 26, 2020 UH News
A University of Hawaiʻi Institute for Astronomy (IfA) astronomer has revealed critical new findings linked to a large asteroid expected to pass extremely close to Earth. Dave Tholen and collaborators have announced the detection of Yarkovsky acceleration on the near-Earth asteroid Apophis. This acceleration arises from an extremely weak force on an object due to non-uniform thermal radiation. This force is particularly important for the asteroid Apophis, as it affects the probability of an Earth impact in 2068.

All asteroids need to reradiate as heat the energy they absorb from sunlight in order to maintain thermal equilibrium, a process that slightly changes the orbit of the asteroid. Prior to the detection of Yarkovsky acceleration on Apophis, astronomers had concluded that a potential impact with Earth in 2068 was impossible. The detection of this effect acting on Apophis means that the 2068 impact scenario is still a possibility.

Apophis is noteworthy because of its extremely close approach to the Earth on Friday, April 13, 2029, when the 300 meter-sized asteroid will become visible to the unaided eye as it passes within the belt of communications satellites orbiting the Earth.

“We have known for some time that an impact with Earth is not possible during the 2029 close approach,” said Tholen, who has been accurately tracking the motion of Apophis in the sky since his team discovered it in 2004. “The new observations we obtained with the Subaru telescope earlier this year were good enough to reveal the Yarkovsky acceleration of Apophis, and they show that the asteroid is drifting away from a purely gravitational orbit by about 170 meters per year, which is enough to keep the 2068 impact scenario in play.”

The orbit calculations were performed by Davide Farnocchia of the Jet Propulsion Laboratory, who is a co-author on the paper that was presented at the 2020 virtual meeting of the Division for Planetary Sciences of the American Astronomical Society.

Further observations to refine the amplitude of the Yarkovksy effect and how it affects Apophis’ orbit are underway. Astronomers will know well before 2068 if there is any chance of an impact.

Hey @c.a. , the thread is called 'Near-Earth objects and close calls' and above you have posted a video tweet of a moon halo, which isn't really related to the topic and should go elsewhere.

Earlier you posted a tweet about 'the world's second largest meteorite discovered', but that was 'discovered' back in 2016. It is related, but it's old news. Did you realise that? And, if so, you could have made a note making that point clear.

I'm bringing it to your attention because you appear to be posting in a hurry and without thinking it through. Nor are you doing so in a manner that is considerate to readers.

It has also already been mentioned on the forum a number of times that, when posting, everyone should provide a brief introduction on what they are posting, and, if necessary, why. In addition, when quoting text from an article, the text should go into a 'quote box'.

Doing all the above will help readers and i think it will also help you.

Agree with itellsya. Lately @c.a. you seem to be posting a lot of noise and not so much signal. Take for example in the Belarus thread, the last few posts by you, starting here, have nothing to do with Belarus. Not sure why you are making the connections you are, but please consider the reader when posting and try to make it clear in your own words why you feel the information you are sharing is useful/important in the context of the thread you are posting in.
