An exoplanet is any planet beyond our solar system. Most of them orbit other stars, but some free-floating exoplanets, called rogue planets, are untethered to any star. We’ve confirmed more than 5,600 exoplanets out of the billions that we believe exist.

JPL is at the forefront of a burgeoning and fascinating endeavor — developing technologies to hunt for exoplanets, which are planets beyond our solar system.

What is an exoplanet? The worlds orbiting other stars are called “exoplanets,” and they come in a wide variety of sizes, from gas giants larger than Jupiter to small, rocky planets about as big around as Earth or Mars. They can be hot enough to boil metal or locked in deep freeze.

In little more than a generation, we’ve gone from knowing only of our own solar system to finding thousands of more distant worlds, known as exoplanets. As new exoplanet discoveries continue to pour in, scientists are building an ever-more-complete catalog of the worlds that grace our galaxy.

Researchers confirmed an exoplanet, a planet that orbits another star, using NASA’s James Webb Space Telescope for the first time. Formally classified as LHS 475 b, the planet is almost exactly the same size as our own, clocking in at 99% of Earth’s diameter.

Learn how NASA's James Webb Space Telescope detected an Earth-sized, rocky planet orbiting a red dwarf star 41 light-years away. See the spectrum, light curve, and illustration of LHS 475 b, a possible Venus-like world.

Exoplanets are planets that orbit stars other than the sun and thus exist outside the solar system. The word "exoplanet" derives from the term "extrasolar planet," which hints at its existence...
