Comets, Asteroids, and Meteorites

What’s the difference? Asteroid:A relatively small, inactive body, composed of rock, carbon or metal, which is orbiting the Sun.

Comet Comet:A relatively small, sometimes active object, which is composed of dirt and ices. Comets are characterized by dust and gas tails when in proximity to the Sun. Far from the Sun it is difficult to distinguish an asteroid from a comet.

Haley’s Comet Visible every years Composed of: H20, NH4, CO2 and dust

Meteroid Meteoroid:A small particle from an asteroid or comet orbiting he Sun.

Meteor Meteor:A meteoroid that is observed as it burns up in the Earth's atmosphere - a shooting star.

Meteorite Meteorite:A meteoroid that survives its passage through the Earth's atmosphere and impacts the Earth's surface.
