Aspirin is a drug that was originally made from willow bark. It is a commonly used painkiller for mild pain. It also thins the blood slightly and can be used to help people who get blood clots, but conversely might cause excessive bleeding and it is not recommended to take aspirin before you have surgery.

An asteroid is very similar to a comet - it is a large rock that orbits the sun. Comets have a tail, while asteroids do not.
Smaller rocks, from the size of a grain of sand to a large bounder are called meteoroids. When they enter the Earth's atmosphere, they are called meteors. If they hit the ground, they are called meteorites. The photo is of a meteorite.
