Extrasolar object

Extrasolar (From extra, Latin for outside or beyond, and solar, Latin for the Sun) is a term applied to any object that exists outside the Solar System. It is not applied to stars, or any other celestial object that is larger than a star or the Solar System, such as a galaxy. It is only used for objects (aside from stars) which are also found in the Solar System. The terms for extrasolar examples of Solar System bodies are:

• Extrasolar planet, also called an "exoplanet"
• Extrasolar moon, also called an "exomoon"
• Exocomet, an extrasolar comet
• Extrasolar asteroid, with one identified as of 2013, orbiting GD 61

Some Solar System object classes, such as minor planets, dwarf planets and Trans-Neptunian objects have not been detected outside the Solar System.
