Planets are celestial bodies that orbit stars, formed from the gas and dust of young solar systems. They come in a wide variety—from rocky worlds like Earth and Mars to gas giants like Jupiter and ice giants like Neptune. Studying planets helps scientists understand how solar systems form and evolve, including the conditions that might support life. This field includes both planets in our own solar system and exoplanets, planets orbiting stars beyond the Sun, discovered by powerful telescopes and space missions. This page features the latest research and discoveries about planets, their atmospheres, surfaces, and potential habitability.
