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


Exoplanets are of interest to researchers and ufologists in determining if alien intelligence is possible in interstellar space. Gliese 581 c and HD 113766 are extrasolar planets within potential habitable zones. If Goldilocks conditions exist in those star systems, such exoplanets could be candidates for extraterrestrial life, beyond just extraterrestrial bacteria.
