An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not then recognized as such. The first confirmed detection of an exoplanet was in 1992 around a pulsar, and the first detection around a main-sequence star was in 1995. A different planet, first detected ...
Motion interpolation of seven images of the HR 8799 system taken from the W. M. Keck Observatory over seven years, featuring four exoplanets. This is a list of extrasolar planets that have been directly observed, sorted by observed separations. This method works best for young planets that emit infrared light and are far from the glare of the star.
This is a list of transiting extrasolar planets sorted by orbital periods. As of 2024, 4195 transiting exoplanets have been discovered. [1] This list consist of all transiting exoplanets through 2012, and notable discoveries since. All the transiting planets have true masses, radii and most have known inclinations
There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets. Artist's concept of the potentially habitable exoplanet Kepler-186f As of 14 January 2025, there are 5,819 confirmed exoplanets in 4,346 planetary systems , with 974 systems having more than one planet .

This list of exoplanets discovered in 2025 is a list of confirmed exoplanets that were first reported in 2025. For exoplanets detected only by radial velocity , the listed value for mass is a lower limit.
The number of confirmed exoplanets — planets orbiting stars other than the sun — has risen to 5,438, with 9,600 more candidates under review. Most of these are in the Milky Way, though ...
The planet is located some 1,200 light-years away. A light-year is 5.8 trillion miles. It's the second-lightest exoplanet found so far based on its dimensions and mass, according to the researchers.
This list of exoplanets discovered in 2021 is a list of confirmed exoplanets that were first observed in 2021. For exoplanets detected only by radial velocity, the listed value for mass is a lower limit. See Minimum mass for more information.
