A scientist is tracking an object orbiting the Sun that is found between Mars and Jupiter. Which additional feature can be used to determine the object is an asteroid?

Asteroids are rocky or metallic bodies, and many have irregular shapes because their gravity is too weak to make them round. A coma or an ice-and-dust tail is associated with comets, while a streak of light is a meteor seen in an atmosphere. The correct choice is “has an irregular shape.”
