ALT This image shows the most massive planet-hosting star pair to date, b Centauri, and its giant planet b Centauri b. The star pair, which has a total mass of at least six times that of the Sun, is the bright object in the top left corner of the image, the bright and dark rings around it being optical artifacts. The planet, visible as a bright dot in the lower right of the frame, is 10 times as massive as Jupiter and orbits the pair at 100 times the distance Jupiter orbits the Sun. The other bright dot in the image (top right) is a background star. By taking different images at different times, astronomers were able to distinguish the planet from the background stars.

In December 2021, astronomers announced the discovery of b Cen AB b, an imaged planet that orbits two stars, each more massive than any other star known to host planets.
