A) orbit at twice its distance from Earth.
B) orbit at four times the distance from Earth.
C) escape Earth.

Based on what you have learned, what is the most likely explanation for the lack of asteroids between Mercury and Mars? A) There were very few planetary leftovers in this region, because most of the solid material was accreted by the terrestrial planets as the planets formed. B) It was too hot for asteroids to form in this part of the solar system. C) Gravity was too weak to allow asteroids to form in this part of the solar system. D) All the asteroids that formed between Mercury and Mars later migrated to the asteroid belt between Mars and Jupiter.
