Extrasolar object

An extrasolar object 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. 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
Exoasteroid, an extrasolar asteroid

Some Solar System object classes, such as minor planets, dwarf planets and Trans-Neptunian object equivalents have not been detected outside the Solar System. Several exocomets have passed near or through the solar system, and are called interstellar interlopers.
