About PlanetDB

PlanetDB is a reference database of 143 celestial bodies from our solar system and beyond: the eight planets, 9 dwarf planets, major moons, asteroids, comets, centaurs, trans-Neptunian objects, nearby stars and 13 well-known exoplanets.

Each entry lists its category, the system or region it belongs to, its diameter and orbital period where they are known, and a short summary of what makes it notable. Browse by category or system from the home page, or use the search box to find a body by name or keyword.
