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)
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 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. [17] [18] [19]
The host star of the exoplanet is TOI-3235, a M-type main sequence star (red dwarf) that is not visible to the naked eye from Earth with a apparent magnitude of 14.5. [4] The star has a mass of 0.394 ± 0.003 M ☉, a radius of 0.3697 ± 0.0018 R ☉ and a temperature of 3388 ± 68 Kelvin. [3] It is located 237 light-years away in the ...
A potentially habitable exoplanet that is roughly similar in size to Earth has been found in a system located 40 light-years away, according to a new study.
In 2012, Johnson's team discovered three small rocky exoplanets in a red dwarf star system observed with the Kepler space telescope. [13] The system was renamed Kepler-42 and the outermost planet was found to be nearly as small as Mars , making it the smallest known exoplanet at the time. [ 14 ]
NASA Exoplanet Exploration Program "travel poster" for HD 40307 g. HD 40307 g is an exoplanet candidate suspected to be orbiting in the habitable zone of HD 40307.It is located 42 light-years away in the direction of the southern constellation Pictor.
