55 Cancri system

A binary star system. The main component is a yellowish main sequence star, known as 55 Cancri A. The second component, 55 Cancri B, is a red dwarf and orbits the main star at a distance of 1065 AU (1 AU = 150 million km). It takes this red dwarf thousands of years to complete an orbit around the main star.
