First directly imaged extrasolar planet (infrared) 2M1207 b: 2M1207: 2004/ 2005 May be a sub-brown dwarf instead of a planet, depending on formation mechanism and definitions chosen. If it is a planet, it is the first known planet around a brown dwarf. First directly imaged extrasolar planet orbiting a 'normal' star (infrared) DH Tauri b: DH ...
The ECWG's rules for naming exoplanets are identical to those adopted by the Minor Planet Center for minor planets. [2] Names are a single word consisting of sixteen characters or less, pronounceable in some language, non-offensive, and not identical to existing proper names of astronomical objects. [3]
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.

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.

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.
The exoplanet naming convention is an extension of the system used for naming multiple-star systems as adopted by the International Astronomical Union (IAU). For exoplanets orbiting a single star, the name is normally formed by taking the name of its parent star and adding a lowercase letter.
