Final answer:
Asteroids are rocky bodies orbiting the Sun, predominantly located in the asteroid belt between Mars and Jupiter, and range from 30 meters to several hundred kilometers in width. They comprise different types, including carbonaceous, stony, and metallic. Hence, the answer is 'all of the above'.
Step-by-step explanation:
Which of the following describes an asteroid?
- Mostly made of silicon-based rock
- Keep a regular orbit
- Between 30 m and several hundred km wide
- Most exist in a ring between Mars and Jupiter
- All of the above
Asteroids are rocky bodies that orbit the Sun, with most found in the asteroid belt between Mars and Jupiter. Most asteroids are remnants of the protoplanetary materials that existed before the planets formed, and they range in size from small boulders to objects spanning hundreds of kilometers.
They mostly consist of carbonaceous materials or stony materials, with a few composed of metals.
