HR 8799 is a young (about 60 million years old) main-sequence star of spectral type A5 V located 128 light-years from Earth in the constellation Pegasus. While some Lambda Boötis stars have sulfur abundances similar to that of the Sun, this is not the case for HR 8799; the sulfur abundance is only around 35% of the solar level. It tied for the first direct image ever taken of planets outside our celestial neighborhood. Hence, there may be an unexplained misalignment between the rotation of the star and the orbits of its planets. These objects are near the upper mass limit for classification as planets; if they exceeded 13 Jupiter masses, they would be capable of deuterium fusion in their interiors and thus qualify as brown dwarfs under the definition of these terms used by the IAU's Working Group on Extrasolar Planets. HR 8799 adalah bintang urutan utama berusia 30 juta tahun terletak 129 tahun cahaya (39,6 parsec) dari Bumi di konstelasi Pegasus.

HR 8799 is a young Lambda Boötis star in the constellation of Pegasus. The spectrum of planet e is similar to a reddened spectrum of Saturn. λ Boötis stars like this are generally young, with a mean age of a billion years. Specifically, it is easier to obtain images when the planet is especially large (considerably larger than Jupiter), widely separated from its parent star, and hot so that it emits intense infrared radiation. Despite the large masses, warm temperatures, and brown dwarf-like luminosities, they failed to detect any emissions at 5 GHz down to a flux density detection threshold of 1.04 mJy. More accurately, asteroseismology also suggests an age of approximately a billion years.
