An extrasolar object ({{ety|la|extra|outside or beyond||solaris|of the Sun}}) is an astronomical object that exists outside the Solar System.

- Extrasolar planet, also called an "exoplanet"
- Extrasolar moon, also called an "exomoon"

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