51 Pegasi B. Artwork of the planet 51 Pegasi B near its sun,the star 51 Pegasi (upper right). Concentric rings of aurorae can be seen around the planet's pole,with flashes of lightning scattered across its surface. The asteroid-like moon (lower right) in orbit around 51 Pegasi B has been heated to red-hot temperatures by the nearby sun. 51 Pegasi is a Sun-like star some 42 light years from Earth. 51 Pegasi B is about half as massive as Jupiter,and orbits only 7 million kilometres from the star,equivalent to 1/6th of Mercury's orbit around the Sun. Aurorae and lightning are found on the gas giants in the solar system,and would be expected on 51 Pegasi B | |
