List of extrasolar planets directly imaged
From Wikipedia, the free encyclopedia
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.
The most massive directly imaged planet is κ And b, which masses 12.8 MJ; the least massive is Fomalhaut b, which masses 2 MJ. The widest planet-star separation is GJ 3483 b, which is 2500 AU; the shortest separation is 2M J044144b, which is 2.0 AU.
There are 4 members of multi-planet systems, all orbiting around HR 8799.
Yellow rows denote the members of the multi-planet system
