    List of directly imaged exoplanets GudangMovies21 Rebahinxxi LK21

    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. 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 planets.
    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 coldest and oldest planet directly imaged is Epsilon Indi Ab, which has six times Jupiter's mass, an effective temperature of 275 K, and an age of about 3.5 Ga.
    This list includes the four members of the multi-planet system that orbit HR 8799.
    It is unlikely or at least unclear if objects on a wide orbit (≥100 AU) formed in circumstellar disks and these objects are therefore more often referred as planetary-mass companions. Only in rare cases, such as for HD 106906 b, the formation of the object in the disk is seen plausible.


    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 Images


    Exoplanets


    Although listed in the table below, the identities of Candidate 1, FW Tau b, 2MASS J044144 b, and HD 100546 b are disputed. They may not actually be true exoplanets.
    † There is no consensus whether these companions of stars should be considered sub-brown dwarfs or planets
