47 ursae majoris b

After the discovery of the first extrasolar planet around a Sun-like star, 51 Pegasi b, astronomers Geoffrey Marcy and R. Paul Butler searched through their observational data for signs of extrasolar planets and soon discovered two: 47 Ursae Majoris b and 70 Virginis b. A more recent study with datasets spanning over 6,900 days came to the conclusion that while the existence of a second planet in the system is likely, periods around 2,500 days have high false-alarm probabilities. The residuals scatter by 11 m s-1 from a Keplerian fit to the 34 velocity measurements obtained during 8 yr. The best solution gives a period of 7,586 days (almost 21 years), which would place the planet at 7.73 AU from the star. 47 Ursae Majoris (abbreviated 47 UMa), formally named Chalawan /ˈtʃɑːləwən/, is a yellow dwarf star approximately 46 light-years from Earth in the constellation of Ursa Major. 47 Ursae Majoris b orbits at a distance of 2.14 AU from its star, taking 1,095 days to complete a revolution. 47 Ursae Majoris b va ser descobert, com la majoria de planetes extrasolars coneguts, detectant els canvis en la velocitat radial de l'estrella.
