A meteor, or shooting star, is a streak of light that is caused by the friction when a meteoroid from space enters the Earth's atmosphere. And, meteorites are space rocks that survive the friction of the atmosphere and land on Earth.You may see a meteor streak through the sky on any night.he rocks in space are sometimes called small bodies. Some of them are larger and are called minor planets or planetoids. They may also be known as NEOs -- Near Earth Objects. Whatever they may be called, they have much to tell us about our solar system.
