...Whether it was from space, falling from a plane, or dropped by another person high above, it would fall at the same "terminal
velocity", no matter where it fell from. So a small meteorite that size might only be moving at only 150 mph....
This is correct. meteorites of this size will fall at the same maximum speed that it would if simply dropped from -- say -- 10,000 feet up. That is
the terminal velocity.
People are under the mistaken
impression that small meteorites would be moving at thousands of miles per hour and are fiery balls as they hit
the ground. This is not true at all. Let's blame Hollywood for that myth.
Small meteorites (such as the size of the object seen in the video) would be moving fast in space, but they REALLY get slowed down quite a bit after
encountering Earth upper atmosphere, and by the time they get down to the lower atmosphere (such as where planes fly), they would have slowed down to
terminal velocity, which is the maximum velocity something dropped from above would fall. A skydiver freefalls at terminal velocity of about 150 mph
to 200 mph in the lower atmosphere (exact velocity is based on mass and shape of the skydiver)
So a meteorite the size of the object in the video would not be falling so fast that it would mack a huge crater (maybe a small depression in the
ground, but not a crater). The picture below is an example of a small-ish meteor. This is the Peekskill Meteorite
that fell back in 1992 --
named for the town of Peekskill, NY where the only known piece of it landed. As you can see, it was moving only fast enough (maybe 150 mph or 200
mph) to put a huge dent in a parked car, but it really wasn't moving like you see in a Hollywood movie.
