47 Ursae Majoris d

Extrasolar planet in the constellation Ursa Major

47 Ursae Majoris d (sometimes abbreviated 47 Uma d) is an extrasolar planet approximately 46 light-years away in the constellation of Ursa Major. The planet was discovered located in a long-period orbit (38 years) around the star 47 Ursae Majoris. As of 2011, it is the outermost of three known planets in its planetary system. It has a mass of at least 1.64 times that of Jupiter. It is the longest-period planet detected by Doppler spectroscopy. The evidence of this planet was found by Bayesian Kepler periodogram in March 2010.[1]
