The objects that typically orbit the sun at approximately 3 AU are asteroids.

Here's why:

* The Asteroid Belt: The asteroid belt lies between the orbits of Mars and Jupiter, spanning roughly from 2 to 4 AU.

* Average Distance: 3 AU falls within this range, making it a typical distance for asteroids.

While other objects might occasionally pass through or reside near 3 AU, asteroids are the most common celestial bodies found in that region.
