The first extrasolar planet found to have a density compatible with being a rocky planet is CoRoT-7b in 2009. 55 Cancri e was found to be a terrestrial planet in 2011. First super-Earth orbiting a main sequence star [NB 2] Gliese 876 d: Gliese 876: 2005 Orbits a red dwarf star. First icy extrasolar planet orbiting a main sequence star OGLE-2005 ...
51 Pegasi b: In 1995 this became the first exoplanet orbiting a main-sequence star to have its existence confirmed.It is a hot Jupiter with a 4.2-day orbit. [12]47 Ursae Majoris b: In 1996 this Jupiter-like planet was the first long-period planet discovered, orbiting at 2.11 AU from the star with the eccentricity of 0.049.
This is the list of 20 extrasolar planets that were detected by timing –– 8 by pulsar timing and 12 by variable star timing, sorted by orbital periods. It works by detecting the changes in radio emissions from pulsars caused by the gravity of orbiting planets. Same thing works for variable stars, not by radio but light.
Astrometry has been used to discover a handful number of exoplanets, mostly gas giants more massive than Jupiter. It is based on measuring a star's proper motion, and seeing how that position changes over time: a planet with a sufficiently large mass is able to gravitationally pull its host star, making its proper motion vary over large timescales.
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.
An artist's rendition of Kepler-62f, a potentially habitable exoplanet discovered using data transmitted by the Kepler space telescope. The list of exoplanets detected by the Kepler space telescope contains bodies with a wide variety of properties, with significant ranges in orbital distances, masses, radii, composition, habitability, and host star type.
Scientists say they are rethinking how the weather works after creating a 3D map of an exoplanet 900 light-years away and discovering a world with jet streams fueling wild storms.
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.
