An asteroid hit Russia last month, and very likely was an asteroid before that.
"The asteroid belonged to the Apollo group of near-Earth asteroids,[4][6] and was roughly 40 days past perihelion[81] (closest approach to the Sun) and had aphelion (furthest distance from the Sun) in the asteroid belt.[4][81] "

Meteorites could be from the asteroid belt, or not. If formed beyond the frost line, they were comets.
