Nov 3, 2024 · Asteroids, sometimes called minor planets, are rocky remnants left over from the formation of our solar system about 4.6 billion years ago. Most asteroids can be found orbiting our Sun between Mars and Jupiter within the main asteroid belt.

An asteroid is a minor planet —an object larger than a meteoroid that is neither a planet nor an identified comet —that orbits within the inner Solar System or is co-orbital with Jupiter (Trojan asteroids).

Jan 17, 2025 · Asteroids, sometimes called minor planets, are rocky, airless remnants left over from the early formation of our solar system about 4.6 billion years ago. Most asteroids can be found orbiting the Sun between Mars and Jupiter within the main asteroid belt.

Mar 31, 2014 · About once a year, an automobile-sized asteroid hits Earth’s atmosphere, creates an impressive fireball, and burns up before reaching the surface. Every 2,000 years or so, a meteoroid the size of a football field hits Earth and causes significant damage to the area.
