4 Ursae Majoris b

4 Ursae Majoris b, also known as Pi Ursae Majoris b, is an extrasolar planet orbiting the star 4 Ursae Majoris, approximately 252 light-years away in the constellation of Ursa Major. The mass is calculated to be over 7 times more than Jupiter, classifying as mid-superjovian (Ib). It eccentrically orbits the star a little bit closer than Earth to the Sun, but it takes only three-fourths of a year in period. This makes the orbital velocity 12% fast... more

4 Ursae Majoris b, also known as Pi Ursae Majoris b, is an extrasolar planet orbiting the star 4 Ursae Majoris, approximately 252 light-years away in the constellation of Ursa Major. The mass is calculated to be over 7 times more than Jupiter, classifying as mid-superjovian (Ib). It eccentrically orbits the star a little bit closer than Earth to the Sun, but it takes only three-fourths of a year in period. This makes the orbital velocity 12% faster than the Earth. It has a fast semi-amplitude of 215.6 m/s because the planet is a mid-superjovian that orbits slightly closer than Earth to the star. The radius is probably slightly smaller than Jupiter and has a very strong gravitational pull. less
