What’s the Difference Between a Comet, Asteroid and Meteor?

What’s the Difference Between a Comet, Asteroid and Meteor?

Where asteroids are located?

  • Most asteroids lie in a vast ring between the orbits of Mars and Jupiter.
  • Not everything in the main belt is an asteroid, for instance, comets have recently been discovered there, and Ceres, once thought of only as an asteroid, is now also considered a dwarf planet.
  • Many asteroids lie outside the main belt. For instance, a number of asteroids called Trojans lie along Jupiter’s orbital path.
  • Three groups — Atens, Amors, and Apollos — known as near-Earth asteroids orbit in the inner solar system and sometimes cross the path of Mars and Earth.
  • Asteroid: A relatively small, inactive, rocky body orbiting the Sun.
  • Comet: A relatively small, at times active, object whose ices can vaporize in sunlight forming an atmosphere (coma) of dust and gas and, sometimes, a tail of dust and/or gas.
  • Meteoroid: A small particle from a comet or asteroid orbiting the Sun.
  • Meteor: The light phenomena which results when a meteoroid enters the Earth’s atmosphere and vaporizes; a shooting star.
  • Meteorite: A meteoroid that survives its passage through the Earth’s atmosphere and lands upon the Earth’s surface.
