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 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.

Exoplanets have been discovered using several different methods for collecting or combining direct images to isolate planets from the background light of their star. Non-Redundant Aperture Masking Interferometry is a method of combining the views of multiple telescopes into a single image, while the other methods are algorithms for combining ...
The first confirmation of an exoplanet orbiting a main-sequence star was made in 1995, when a giant planet was found in a four-day orbit around the nearby star 51 Pegasi. Some exoplanets have been imaged directly by telescopes, but the vast majority have been detected through indirect methods, such as the transit method and the radial-velocity ...
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.
The Neptunian desert or sub-Jovian desert is broadly defined as the region close to a star (period < 2–4 days) where no Neptune-sized (> 0.1 M J) exoplanets are found. [1] This zone receives strong irradiation from the star, meaning the planets cannot retain their gaseous atmospheres: they evaporate, leaving just a rocky core. [2]
A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, ... free refills for some drinks. Lighter Side. Lighter Side.
K2-33b (also known by its EPIC designation EPIC 205117205.01) is a very young super-Neptune exoplanet, orbiting the pre-main-sequence star K2-33.It was discovered by NASA's Kepler space telescope on its "Second Light" mission.
