If, for example, it were a much denser asteroid, I mean with a different composition, such as iron, would the result be the same? Thank you!!!
Line-2
Of course not. The consistency, internal structure and composition of the asteroid count a lot in the result. But most potentially dangerous asteroids are like Dimorphs: piles of rubble #RubblePiles
This recent incident claimed that a bullet had breached the cabin while landing.

Three Near-Earth Asteroids Were Hiding in the Sun’s Glare
One of them, which measures nearly one mile wide, might cross paths with Earth in the distant future

Make a wish! Meteor fireball seen over Utah
Many in northern Utah got that chance Thursday after seeing a streaking beam of light that was most likely a meteor.

This morning a bright fireball of the Leonid meteor shower streamed by at 5:17:25 on November 17, 2022, as captured by a camera pointed southeast from Hiratsuka, Japan. It left a beautiful green meteor trail. The Leonid meteor shower will reach its peak at dawn on November 18. (T.Deepl)

Some visible comets coming into view soon. This table lists the visible comets for the coming 3 months. Note that comets 96P/Macholz and C/2022 E3 should be visible by end January and beginning February 2023.
Use Skylive to determine the comets location (remember to change location to Your Location from the default Greenwich, UK). Once you have the correct location, a list below tells you what is visible or not depending on the time of the day.
Use this table to determine visibility magnitude.

The Night the Stars Fell
This famous engraving of the 1833 Leonid meteor shower was produced for the Adventist book Bible Readings for the Home Circle by Adolf Vollmy. It’s based on a painting by Swiss artist Karl Jauslin, which, in turn, was based on a first-person account of the 1833 storm by a minister, Joseph Harvey Waggoner, who saw the 1833 shower on his way from Florida to New Orleans.
In that famous shower, hundreds of thousands of meteors per hour were seen! It was the first recorded meteor storm of modern times. Read more about the 1833 Leonid meteor shower in this post.

Check out this old engraving of the November 1833 Leonid meteor shower. It's one reason this shower - due to peak this weekend - is so famous.earthsky.org

Last night on my final walkabout (~12:30) before bed, I saw this meteor. I have never seen a green meteor before and this one was really green!

My niece living in Norway sent this article to me this morning.
Although the pictures and article are from today, this sighting happened on October 30th.
The trajectory of the object, or objects came from the direction of the Ukraine, over Sweden, and then broke up over Norway so the suspicion that it may have been a man made projectile, or weapon had to be analyzed.
I’ve included some of the details, translated into English:
“Video cameras on Gaustatoppen in Telemark captured the incident. It happened at 04:54 on the night of 30 October.
- This is something we cannot explain, says Morten Bilet in the Norwegian Meteor Network.
The lights look like meteors. There are fast moving lights in the sky.
Meteors are not an uncommon sight. If you look up when the stars are clear, you will almost certainly see a meteor within an hour. Nevertheless, what happened on 30 October is far from the norm.”
“It is completely unique that so many meteors should appear in the night sky in such a short time. So we don't know where this is coming from, or what the cause is, says Bilet.
In the video from the event, it is clear that all 23 objects come out of the same point in the sky.”[…]
“This was an extended beam of objects that arrived at Earth at approximately the same time, explains Midtskogen.
The video recordings also provide information about the speed of the objects.
- They came quickly. 64 kilometers per second. That is much higher than the speed of what we humans have sent into space. So this is not space junk, says Midtskogen.”

Noe ukjent har truffet Norge
I løpet fem sekunder registrerte kameraer i Telemark 23 ukjente objekter på himmelen. De beveget seg i ekstremt høy hastighet og brant opp. Ekspertene kan ikke forklare hva det var.

I wonder if they are related. Perhaps a minor precursor may be related events representing a very very small cluster!

Asteroid hit Canada mere hours after discovery
Astronomers spotted an asteroid just hours before it impacted with Earth this morning (November 19, 2022), near Lake Erie. This is not the first time this year astronomers have discovered a rock from space just hours before it hit Earth. But this time, it impacted over a populated area, crossing the skies of Toronto, Canada. So we have video and witnesses who said they saw, heard and felt the impact.
Ye Quanzhi, a University of Maryland astronomer who studies asteroids, comets and meteors, reported on Twitter at 1:13 a.m. EST on November 19:
He shared the link for NASA’s Center for Near Earth Object Studies Hazard Assessment page. The object, C8FF042, is now removed from the page because it has struck Earth and is therefore no longer a threat.
Precise prediction
At 2:29 a.m. EST, Richard Moissl tweeted that the asteroid should impact around 8:26 UTC, which translates to 3:26 a.m. EST. That turned out to be incredibly accurate, as cameras around Toronto captured the bolide at 3:25 and 3:26 a.m. The CN Tower cam in Toronto was one of the cameras that saw the asteroid’s nearly horizontal entry.

You know what? I had a much closer look at the report that I linked to, which is the same one you linked to from AMS, and I realize that the one that I saw was not the same event. The report we linked to happened in the southwest corner of Alberta at ~6:25 am MST, Nov. 17. The one I saw was south-central around ~12:30 am MST, Nov. 18. The two are completely different events. Along with the other reports, it does look like it might have been a small cluster.

6th asteroid discovered just before hitting Canada yesterday: #2022WJ1 Fortunately they have all been a few meters in diameter and have only produced falls of #meteorit
Yesterday we observed this BOLID of the TAURIDS While we were enjoying the observation a flash of blue and green light was observed Prades According to reports the @RedSpmn @Josep_Trigo disintegrated at 75km s. n. it shone brighter than the MOON itself! We attest
