How many asteroids crash into the sun in one earth day?

Answer 1

1. Nearly all asteroids are in circular or elliptical orbit around the sun so will not hit it. Gravity does not pull asteroids into the sun - unless an asteroid is heading straight for the sun it will end up being catapulted around it. The only asteroids that will ht the sun are ones knocked out of their normal orbit by a collision or close encounter with another object and knocked in to a trajectory heading straight for the sun.

2. There are asteroids and meteorites of every size from a few miles across down to less than a millimeter. There are obviously much fewer of the larger ones and much more of the smaller ones. Any answer to the question would therefore need to give a number of collisions for objects in each size category. I imagine that it would be very rare for any asteroid big enough to be observed from Earth or satellites to hit the sun.
