Although a meteor may seem to be a few thousand feet from the Earth, [25] meteors typically occur in the mesosphere at altitudes from 76 to 100 km (250,000 to 330,000 ft). [26] [27] The root word meteor comes from the Greek meteōros, meaning "high in the air". [23] Millions of meteors occur in Earth's atmosphere daily.
A meteor shower results from an interaction between a planet, such as Earth, and streams of debris from a comet(or occasionally an asteroid).

Whipple envisioned comets as "dirty snowballs," made up of rock embedded in ice, orbiting the Sun.
