#exoplanets

Explore 6,200+ confirmed planets orbiting other stars, from the NASA Exoplanet Archive. For each exoplanet get its host star, discovery method, year and facility, orbital period, radius and mass (relative to Earth), distance in light-years and equilibrium temperature. Look one up by name, search and filter by discovery method or year, or list every planet in a host system (e.g. TRAPPIST-1). Great for astronomy, education and space apps.

Physical and orbital data for the solar system and beyond: every planet, dwarf planet, major moon and the Sun with NASA fact-sheet values (mass, radius, surface gravity, density, escape velocity, mean temperature, orbital and rotation period, semi-major axis, moon count and rings), plus a searchable catalogue of more than 6,000 confirmed exoplanets from the NASA Exoplanet Archive (radius, mass, orbital period, equilibrium temperature, distance in light-years, host star, discovery year and method). Filter exoplanets by host star, discovery method, year, size or distance, compare solar-system bodies side by side, and look up any single body or exoplanet by name. Every endpoint accepts input via the query string or the request body and returns lean JSON. Pure server-side data (no third-party upstream), so responses are instant and always available. Ideal for education, EdTech, astronomy apps, data visualisation and science tools.
