Asteroids

What are Asteroids?
Asteroids can come really close to the earth and sometimes they come to earth. Sometime you might actually see one but more than likely you won't because they burn up in the atmosphere.
Asteroids can get pretty big in size. Most are the size of a bigger boulder and some can get up to a few miles long. That is a big rock.
Asteroids are usually made up of smaller rocks clumped up together. There can also be other things in them that are flying around.
