This is a list of extrasolar planet
An exoplanet or extrasolar planet is a planet outside the Solar System. The first possible evidence of an exoplanet was noted in 1917 but was not recognized as such. The first confirmation of detection occurred in 1992. A different planet, init ...
s 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. Currently, this list includes both directly imaged planets and imaged planetary-mass companions (objects that orbit a star but formed through a binary-star-formation process, not a planet-formation process). This list does not include free-floating planetary-mass objects in star-forming regions or young associations, which are also referred to as rogue planet
A rogue planet (also termed a free-floating planet (FFP), interstellar, nomad, orphan, starless, unbound or wandering planet) is an interstellar object of planetary-mass, therefore smaller than fusors (stars and brown dwarfs) and without a h ...

The data given for each planet is taken from the latest published paper on the planet to have that data. In many cases it is not possible to have an exact value, and an estimated range is instead provided. The lightest, coldest, and oldest planet directly imaged is Proxima Centauri c
Proxima Centauri c (also called Proxima c or Alpha Centauri Cc) is a controversial exoplanet candidate claimed to be orbiting the red dwarf star Proxima Centauri, which is the closest star to the Sun and part of a triple star syste ...
, which has seven times Earth's mass, an effective temperature of 39 K, and an age of about 4.8Ga.
This list includes the four members of the multi-planet system that orbit HR 8799
HR 8799 is a roughly 30 million-year-old main-sequence star located away from Earth in the constellation of Pegasus. It has roughly 1.5 times the Sun's mass and 4.9 times its luminosity. It is part of a system that also c ...

Key
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 multiple direct images taken from the same telescope. * ADI = Angular Differential Imaging *KLIP = Karhunen–Loève Image Processing * LOCI = Locally Optimized Combination of Images * NRM = Non-Redundant Aperture Masking Interferometry * RSDI = Reference Star Differential Imaging *SDI = Spectral Differential Imaging * TLOCI = Template Locally Optimized Combination of ImagesExoplanets
Although listed in the table below, the identities of Fomalhaut b and Candidate 1 are disputed. They may not actually be true exoplanets. sub-brown dwarf A sub-brown dwarf or planetary-mass brown dwarf is an astronomical object that formed in the same manner as stars and brown dwarfs (i.e. through the collapse of a gas cloud) but that has a planetary mass, therefore by definition below the limi ...See also
