DH Tauri b and GQ Lupi b were confirmed as companions within about three month in 2005. Both could be brown dwarfs. If one is a planet, it is the first planet orbiting a 'normal' star, possibly the first exoplanet directly imaged. First directly imaged extrasolar planet orbiting a sun-like star (infrared) AB Pictoris b AB Pictoris: 2005
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.
Animation showing exoplanets by year from 1991 until 2022 (March) with a total of 5005 discoveries. [1] An exoplanet (extrasolar planet) is a planet located outside the Solar System. The first evidence of an exoplanet was noted as early as 1917, but was not recognized as such until 2016; no planet discovery has yet come from that evidence. [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.

These are lists of planets.A planet is a large, rounded astronomical body that is neither a star nor its remnant. The best available theory of planet formation is the nebular hypothesis, which posits that an interstellar cloud collapses out of a nebula to create a young protostar orbited by a protoplanetary disk.
This is the list of years when at least one confirmed exoplanets were discovered. This is a container category . Due to its scope, it should contain only subcategories .
