Systems
Planetary systems grouped by host galaxy. Each entry connects a star with its confirmed worlds and any candidates still under review.
In the Milky Way
The Solar System
Eight planets, one G-type star, and an animated diagram that follows the current date.
Proxima Centauri
Our nearest stellar neighbor, 4.24 light-years away. Two confirmed planets and one candidate orbit a small, flare-active red dwarf.
TRAPPIST-1
Seven Earth-sized planets in a compact, resonant chain around an ultracool dwarf 40 light-years away.
TOI-700
A calm red dwarf 100 light-years away with four planets, including two Earth-sized worlds in its habitable zone.
Teegarden's Star
One of the nearest, quietest red dwarfs, 12.5 light-years away, with two temperate Earth-mass planets and an outer candidate.
In the Whirlpool Galaxy
The first extragalactic system on this site. Individual stars and planets in other galaxies are rarely resolvable; M51-ULS-1 is one of the exceptions.
