Heads up!
...and it's cold outside.
Gun Shows are almost as comical as boat ramps in the Spring.

Terminal velocity of a meteorite is actually slow compared to a bullet. But who needs velocity when you have that kind of mass?

The Sutters Mill asteroid/meteorite in 2012 was tracked by scientists at 64,000 mph according to a Scientific American article. That’s cooking right along.

The Sutters Mill asteroid/meteorite in 2012 was tracked by scientists at 64,000 mph according to a Scientific American article. That’s cooking right along. In space that's likely true. When it hits air resistance, though, friction kicks in and terminal velocity is a bit lower, somewhere between 200 and 400 mph.

That's not right. From what I've been reading, asteroids/meteors it the earth's surface at speeds between 10 and 20 miles per SECOND, so multiple that by 3600 to get miles per hour .. not by 60 which would give you miles per minute. Using those numbers jibes with WAM's citation .. 10-20 miles per second would be 36,000 to 72,000 miles per hour.

The website I looked at assumed the meteor had lost all of it's momentum and was just falling like it had been dropped from a plane.

Guess on my part but the rock that made this hole was moving right along. Probably faster than a Creed ![[Linked Image from postmasburg.co.za]](https://www.postmasburg.co.za/wp-content/uploads/2017/10/morokweng-crater-5.jpg)

Don’t forget that little number that creamed Siberia in 1908.

We visited the meteor crater two years ago and it is an awesome sight. The other memorable aspect of the visit was that the wind was gusting close to 90 mph! We had to hold on tight to the railing on the catwalk and hiking the rim was out of the question. Our granddaughter loved the museum. A visit to the Very Large Array was another high point of that trip. Some neat stuff in the southwest. GD

The chelyabinsk rock was 66 feet long and traveling at >58,000 FPS. It's explosion in the atmosphere injured over 1,000 on the ground who were nowhere near the impact point of it's pieces.
But Tunguska...
There was a meteor to admire. From very far away...
