HD 45364 b is an extrasolar planet located approximately 107 light years away[1] in the constellation of Canis Major, orbiting the 8th magnitude G-type main sequence star HD 45364. Its minimum mass is 63% that of Saturn or 19% that of Jupiter. It takes 227 days to orbit the star at a distance 68% that of Earth’s distance from the Sun.[2] This planet was discovered by HARPS on August 8, 2008 and announced together with HD 45364 c. It is located in a 3:2 orbital resonance with HD 45364 c.
