Space Launch Live maintains a complete, accurate catalog of every major object in our solar system — the Sun, all eight planets, every major moon, all five IAU-recognized dwarf planets, notable asteroids, comets, Kuiper Belt Objects, and the two confirmed interstellar visitors. Each body includes verified physical and orbital data from the NASA NSSDC Planetary Fact Sheets, JPL Horizons, and the IAU Minor Planet Center, plus cross-links to every probe, rover, lander, and satellite tracked on the site.
