About 4.3 days . The parent star is similar to our Sun but it is a little more massive, bigger, brighter, and cooler. 1. Chapter. 51 Pegasi b is the first discovered planet of its parent star, 51 Pegasi. It is the prototype for a new and previously unsuspected class of planet known as epistellar Jovians, or "hot Jupiters," with remarkably small orbits. The 51 Pegasi b Fellowship provides exceptional postdoctoral scientists with the opportunity to conduct theoretical, observational, and experimental research in planetary astronomy.

The first planet found orbiting another Sun-like star has survived a challenge to its existence. The planet orbiting 51 Pegasi … orbital period would be about 2.0 years. The points on the graph indicate actual measurements taken. This object is now known as 51 Peg b. Bellerophon (51 Pegasi b, P13) is a planet that orbits the star 51 Pegasi, located in the constellation Pegasus in the caelregio Testudo 51 light-years away from us. As of 2019, astronomers have discovered more than 4,000 exoplanets. 51 Pegasi is a Sun-like star around which has been discovered a planet, 51 Pegasi b, with about half the mass of Jupiter.With the exception of some pulsar planets, 51 Pegasi b was the first exoplanet to be found. Located some 50 light years away, 51 Pegasi b is the first exoplanet discovered orbiting a main-sequence star and the first known hot Jupiter. N. Houk, University of Michigan, has determined a spectral type of G2-3 V for 51 Peg from a 1-min IIa-O 10-deg objective-prism plate taken on 1981 Aug. 6 with the Burrell Schmidt telescope at Kitt Peak.
