Meteorites are pieces of solid debris usually from a comet or asteroid that have made it to earth. They are considered a meteoroid until they hit earth’s atmosphere at which point they begin to glow from the intense friction. If they don’t completely burn up in the atmosphere and they reach earth they are called meteorites. The largest ones can be damaging and if they are large enough to cause a crater, they are called bolides.
