What is Asteroid?
- Asteroids are small rocky bodies that orbit the sun in a circular orbit.
- These asteroids are often found between Mars and Jupiter’s orbits, but some have more eccentric orbits.
- Asteroids are rocky-metallic structures that range in size from about the size of pebbles to around 600 miles across.
- They are small in size and so they cannot be classified as planets, but they do orbit the Sun.
- They are also known as the leftover stuff of the Solar System.
- Several hundred and thousands of asteroids are known to exist in our Solar System and some are so small that they are yet to be discovered.
