The following year it was unofficially dubbed "Bellerophon" by astronomer Geoffrey Marcy, who followed the convention of naming planets after Greek and Roman mythological figures (Bellerophon was a figure from Greek mythology who rode the winged horse Pegasus).

(Artwork from It has a mass 46 percent that of Jupiter and orbits surprisingly close (7.8 million km [4.8 million miles]) to the star—much closer than Mercury orbits the Sun (at a distance of 57.9 million km [35.9 million miles]). 51 Pegasi B was discovered in 1995 and is just less than half the mass of our solar system's Jupiter. entire habitable zone Oběžná dráha je téměř kruhová (0,03) a trvá 4,2 dne. SETI Institute. However, as per the latest reports, the said planet is a gas giant. HR 3522 exhibits a velocity semiamplitude of 77 m s -1 and a period of 14.65 days, implying a semimajor axis of 0.11 AU and a minimum mass for the companion of M 2 sin i = 0.84MJUP. and Queloz, 1995; and highly circular orbit (e=0.03) that takes only 4.2 days to It has a mass 46 percent that of Jupiter but has a radius 1.9 times that of Jupiter because it is inflated by its star’s heat. Once we have combined Kepler and Newton, then performed the unit conversions we are left with: where P and K are your values for 51 Pegasi b. If a small, rocky (0.472 ± 0.039 MJ) This equation, Mass of 51 Pegasi B, references 1 page 4) It is believed that this particular planet is tidally locked to its star just like our moon is tidally locked to Earth, always exhibiting the same face to it. 51 Pegasi, fifth-magnitude star located 48 light-years away from Earth in the constellation Pegasus, the first sunlike star confirmed to possess a planet.

At the time of discovery, the generally accepted theories of planet formation and evolution could not explain the presence and survival of a Jupiter-size planet at such a short orbital distance. 51 Pegasi B was discovered in 1995 and is just less than half the mass of our solar system's Jupiter.
