An extrasolar object (from extra, Latin for outside or beyond, and solar, Latin for the Sun) is an astronomical 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
