Planets outside our star system. They are either orbiting a different star, or there are rogue planets that move through space without orbiting some other object.

An exoplanet or extrasolar planet is a planet outside the Solar System.

Planets, by definition, orbit the Sun. A celestial body that meets all of the requirements to be a planet with the exception of orbiting the Sun would be an extrasolar planet, or "exoplanet".

So basically just planets outside the solar system. Tatooine or Hoth would both be considered exoplanets. Pandora (from Avatar) is an exoplanet.
