47 Ursae Majoris

A sunlike yellow star which even reminds of our solar system. Two planets have been discovered so far, the bigger with 2.54 times the mass of Jupiter and 2.09 AU distance, the smaller with at least 0.76 times the mass of Jupiter and 3.73 AU distance.
Both orbits are only slightly elliptic which would allow more life-friendly planets inwards.
