Located at a distance of about 50 light years away, the planet 51 Pegasi b is a hot Jupiter, because it has a orbital period less than 10 days (4.23 days) and similar in characteristics with the largest planet in the Solar system, having a mass of about 0.47 mass of Jupiter. 2011 An Extreme Precision Radial Velocity Pipeline: First Radial Velocities from EXPRES 1997 paper, A search for substellar companions to solar-type stars via precise MANDELL A., RAYMOND S. & SIGURDSSON S.

Review Chapter in Treatise on Geophysics, accepted 51 Pegasi is a yellow-orange main sequence dwarf star of spectral and luminosity type G4-5 Va, but it had been previously classified as G2-2.5 and sometimes as a subgiant (IV). Assuming the planet is perfectly grey with no greenhouse or tidal effects, and a Bond albedo of 0.1, the temperature would be 1265 K (approximately 1000 °C / 1800 °F). It's worth noting that 51 Pegasi b is not the first planet outside the solar system to be discovered: In 1992 researchers had spotted planets orbiting dead stars called pulsars.
