Solar
About this site
Solar is a clean, public reference for the solar system: a place to look up the planets, their moons, the dwarf planets, and the great swarm of asteroids, comets and icy worlds beyond Neptune. It is built for the curious — students, hobbyists, educators and sci-fi worldbuilders alike.
This is an astronomy reference, not an astrology site. There are no horoscopes, houses or star signs here — just the physical bodies of the solar system and the measured facts about them.

Use the API yourself
This whole site is just a front end over a free, read-only REST API. You can query the same data directly — see the developer page for a worked example, or browse the interactive API documentation.
Download the whole database
Everything behind this site — every body in the JPL Small-Body Database with every published field, discoveries, close approaches, satellites and the NASA fact sheets — is rebuilt nightly and published as one compressed SQLite file with a manifest, checksum and licence. Get the latest manifest.
