6 OCTOBER 1995, EXACTLY 21 YEARS TODAY FIRST PLANET ORBITING SUN-LIKE STAR WAS FOUNDED
51, pegasi B is the first discovered planetary-mass companion of its parent Star. The planet has been informally named Bellerophon. After its discovery, many term confirmed its existence and obtained more observations of its properties, including the fact that it orbits very close to star, suffers estimated temperatures around 1200c and has a minimum mass about half of Jupiter. At the time, this close distance between the planet and the star was not compatible with theories of planet formation and resulted in discussions of planetary migration. As of 2012, no additional planets had been found orbiting this star.
