Noctis (Latin for "of night") is a space flight simulation video game for Microsoft Windows released in 2000 by Italian programmer Alessandro Ghignola. It centers around first-person visual exploration of the fictional Feltyrion galaxy, which is presented as being approximately 90 thousand light-years in radius — double that of the nonfictional Milky Way Galaxy — and containing over 78 billion stars, many of which host star systems with exoplanets and natural satellites.
