Asteroid swarm: Nasa detects 16 space rocks hurtling towards Earth this week

The largest asteroid from the group is bigger than the Great Pyramid of Giza in Egypt. According to the agency’s Centre for Near-Earth Object Studies (CNEOS), Earth will see a total of seven asteroids fly past on October 8. As noted by CNEOS, these asteroids are 2019 TU, 2019 TW1, 2019 RK, 2019 TC1, 2019 SB6, 2019 TM and 2019 TS.

These asteroids will arrive starting early on Tuesday.

Although most of these asteroids will approach Earth from very safe distances, one of them is expected to fly close to the planet.

According to CNEOS, 2019 T1 will zip past the planet from 0.00378 astronomical units or roughly 351,000 miles away, which is just slightly greater than the distance between the Earth and the Moon.

The next group of asteroids will enter Earth’s locality on October 9.


These asteroids, namely 2019 TV1, 2019 TZ and 2019 SL7 will be heading past Earth early in the morning UK time on this date.

With diameters ranging from 29 to 38 meters, the approaching asteroids are relatively small but would deadly if they made impact.

Asteroid, 2019 TV1 and 2019 TZ will fly past Earth from millions of miles away while 2019 SL7 will approach Earth from a distance of only 0.00363 astronomical units or about 337,000 miles away.

Only one asteroid will zip past Earth on October 10.

It is known as 2019 SX5, this asteroid is the largest one from the group with an estimated diameter of 140 meters.

This Great Pyramid sized asteroid will approach the Earth on October 10.

It should stay at a distance of 0.04533 astronomical units or about 4.2 million miles away.

On Saturday, October 12, Earth will be visited by four more asteroids.

Compared to 2019 SX5, the asteroids 2019 TN1, 2019 SK8, 2019 SV9 and 2019 SE2 are significantly smaller with diameters averaging from 25 to 90 meters.

These four asteroids are expected to visit Earth’s vicinity early on Saturday UK time.

The last asteroid that will fly by Earth this week is called 2019 TT1.

This 38-meter-wide asteroid will approach Earth on October 13 at a distance of 0.00744 astronomical units or about 692,000 miles away.

Nasa has said SL7 will fly around 1.4 lunar distances from the moon - around 538,162 kolmoetres away, meaning the rock will be classed as a near-Earth object (NEO).

The distance will mean Nasa study the asteroid as it passes.

Nasa describes NEOs as comets and asteroids which have been "nudged by gravitational attraction of nearby planets into orbets that allow them to enter the Earth's neighbourhood".

The space agency added: "If we wish to know the composition of the primordial mixture from which the planets formed, we must determine the chemical constituents of the leftover debris from the formation process - the coments and asteroids".

It was recently revealed that NASA is stepping up its preparations to deal with the “God of Chaos” rock Apophis which could arrive in the next 10 years.

Even SpaceX founder Elon Musk has responded by issuing a chilling assessment over our planet’s defence capabilities against artificial intelligence going wrong and an asteroid impact.

Mr Musk said we “currently have no defence” against these huge space rocks.

An asteroid the size of Apophis has the potential to create devastation on a planetary scale.

The last time we saw that was 66 million years ago, when the dinosaurs were wiped out.
Q: (L) Well, thanks a lot! (Ailen) That's a nice way of saying, "No dice!" (L) Okay, as you know, we had a wonderful little exploding comet fragment out there in Russia that did some serious damage and injured lots of people. I'm not glad that it injured lots of people, but I just think it was pretty interesting that this happened like within three days of our new book "Comets and The Horns of Moses" being released in hardcopy. So, I guess the first question is: Anything to tell us about the exploding comet fragment, or whatever they wanna call it? It could have an asteroid, or it could have a comet fragment, or whatever?

A: Denatured comet but who's counting?

Q: (L) Okay. Is that all you're gonna say?

A: Just wait for the next one! That one will be a doozie! And it has "friends!"

The article above is a bummer, see below!

Notice the rest of the statement by the C's, not quoted above:

A: Just wait for the next one! That one will be a doozie! And it has "friends!"

Q: (L) Can you give us a time estimate on that? [laughter] (Belibaste) And location? (L) Location, maybe? (Andromeda) Roughly? Ballpark figures? (Belibaste) Plus size?

A: We would have liked to arrange things so that it could have hit [birds start chirping a lot in the background] on the very day of the book release, however things just don't work that way in the STO reality. Thus, the same applies to predictions of future impacts.

Q: (L) That was a nice way of saying, "No dice!" So there is more out there that's coming, but you can't tell us exactly when, and the next one's gonna be a doozie; so we know that much. Are you saying you know that much?

A: Yes. Please put all former clues together for ballpark figure, keeping in mind that the universe is open thus there will always be variables.
So the above seems to be a prediction about a "future impact". The answer came in context of discussing the Chelyabinsk impact of 2013 in russia in the atmosphere. So that probable future impact might be at least as severe/noticeable as the Chelyabinsk one, while it has "friends".

Also notice that in actuality (from the date of NASA; see here), there are 26 NEO objects scheduled to come very close to earth till November 3rd, out of which a staggering number of 23 NEO objects were discovered just withing the last month! The earliest was discovered September 3rd 2019... Out of those 23 objects, 3 objects are estimated to be between 7 m and 25 m in Diameter; 10 objects are estimated to be between 12 m and 44 m; 6 objects are estimated to be between 20 m and 63 m; 2 objects are estimated to be between 35 m and 92 m and 2 objects are estimated to be between 55 m and 140 m...

The 3 objects out of the total of 26 that are scheduled to come very close to earth till November 3rd and were not discovered within the last month, are the following:

- 162082 (1998 HL1) [discovered 18. April 1998] with an estimated diameter between 440 m - 990 m
- (2017 TG5) [discovered 14. October 2017] with an estimated diameter between 25 m - 57 m
- (2015 JD1) [discovered 11. May 2015] with an estimated diameter between 200 m - 450 m

My layman guess is that some of the smaller objects that were just discovered might travel with one of the two bigger junks listed above.

The 23 object that were discovered just within the last month and now are coming pretty close to earth, were discovered in following sequence:

1 object discovered on September 3rd
2 objects discovered on September 6
2 objects discovered between September 20 and September 22
2 objects discovered on September 24th
2 objects discovered on September 26
3 objects discovered between September 28 and September 30 (every day one new discovery)
1 object discovered on October 2nd
5 objects discovered on October 3rd
5 objects discovered on October 5th

So just within the last week, 12 out of those 23 objects were discovered that are now coming pretty close to earth! Things might be picking up...

Randall Carlson and colleagues discussing the recent close call of „2019 ok“ and the previous huge kilometer sized object discovered with his own moon orbiting it, in the first 17 minutes of his new „Kosmographia“ podcast. See below. Carlson roughly calculates that if „2019 ok“ would have hit, it would have produced the equivalent power of about 28,000 hiroshima bombs (or 19 Tunguska events).

In the words of Carlson:

„People would really be worrying about their ‚save spaces‘ then!“

Carlson also seems to come around the idea now that the difference between Comets and Asteroids might not be as clear cut as it is assumed. He also mentioned that things like these can come in swarms and they discuss the seeming increase of these types of flybys recently:
