Asteroids, comets, and meteors are chunks of rock, ice, and metal left over from the formation of our solar system 4.6 billion years ago. They are a lot like a fossil record of our early solar system. There are currently about 1.4 million known asteroids, and more than 3,900 known comets (including comet fragments).

Quick Facts. Meteoroids are space rocks that range in size from dust grains to small asteroids. When meteoroids enter Earth’s atmosphere, or that of another planet, at high speed and burn up, they’re called meteors. When you see lots if meteors, you’re watching a meteor shower.
Meteors: When meteoroids enter Earth’s atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. Meteorites: When a meteoroid survives a trip through the atmosphere and hits the ground, it’s called a meteorite.

Meteors and Meteorites. www.nasa.gov. “Shooting stars,” or meteors, are bits of interplanetary material falling through Earth’s atmosphere and heated to incandescence by friction. These objects are called meteoroids as they are hur-tling through space, becoming meteors for the few seconds they streak across the sky and create glowing trails.
