Caption. 51 Pegasi is a star that is like our Sun and can be found 15.4 parsecs (50.1 light-years) away from the Earth in the constellation Pegasus. Artist's comparison of the size of the planet 51 Pegasi B (at lower right) with its star, 51 Pegasi (at upper left), and the planets of Jupiter and Earth (at lower right). It is in a class of planets called Hot Jupiters. This year we celebrate the discovery of 51 Pegasi b in October, 1995. The exoplanet is about half the mass of Jupiter, with a seemingly impossible, star-hugging orbit of only 4.2 Earth days. Since then, we’ve figured out it’s likely a Jupiter that formed farther away from 51 Pegasi and migrated inwards towards the star, for one reason or another. 51 Pegasi b (abbreviated 51 Peg b), sometimes unofficially named Bellerophon, is an extrasolar planet approximately 50 light-years away in the constellation of Pegasus. The time it will take to travel to this star is dependent on how fast you are going. 10 Things You Should Know About ’51 Pegasi B’ the First Extrasolar Planet Discovered by Man The 51 Pegasi b or Dimidium is known as the first exoplanet to orbit a sunlike star. This artist’s view shows the hot Jupiter exoplanet 51 Pegasi b, sometimes referred to as Bellerophon, which orbits a star about 50 light-years from Earth in the northern constellation of Pegasus (The Winged Horse).
