First evidence for exoplanet to receive later confirmation. First exoplanets to be confirmed PSR B1257+12 B PSR B1257+12 C: PSR B1257+12: 1992 First super-Earths. [1] These exoplanets orbit a pulsar. First confirmed exoplanet around normal star 51 Pegasi b: 51 Pegasi: 1995 First convincing exoplanet discovered around a Sun-like star. [2]
The exoplanets were found using a statistical technique called "verification by multiplicity". 95% of the discovered exoplanets were smaller than Neptune and four, including Kepler-296f, were less than 2 1/2 the size of Earth and were in habitable zones where surface temperatures are suitable for liquid water.
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 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 confirmation of the detection occurred in 1992. A different planet, first detected in 1988, was confirmed in 2003.

Proper names of planetary systems often follow common themes – for example, the planets of the star Copernicus are named after European astronomers. Proper names for planets outside of the Solar System – known as exoplanets – are chosen by the International Astronomical Union (IAU) through public naming contests known as NameExoWorlds.
This list of exoplanets discovered in 2019 is a list of confirmed exoplanets that were first observed during 2019. [ 1 ] [ 2 ] For exoplanets detected only by radial velocity, the listed value for mass is a lower limit.
