This is a List of exoplanets discovered in 2012. [1] For exoplanets detected only by radial velocity, the mass value is actually a lower limit. (See Minimum mass for more information)
The densest transiting exoplanet known is CoRoT-3b, which has density of 26.4 g/cm 3; the diffusest transiting planet known is Kepler-12b, which has density of only 0.111 g/cm 3. Previously, the longest period of any transiting planets was Kepler-1647b , which takes 1107 days to orbit its (double) stars.

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.
A European Space Agency satellite has observed the shiniest exoplanet ever discovered. The scorching world has reflective clouds made of silicates and titanium.
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]
This is a list of collisions between exoplanets or planetesimals observed in extrasolar systems.These collisions are more common in young systems and are an important part in the growth of especially terrestrial planets from so-called planetary embryos. [1]
