Located about 50 light years from Earth, 51 Pegasi b is a gas giant like Jupiter, with a mass about 150 times that of Earth, circling its host star at a distance of just 7 million km (4.3 million mi.). Astronomers didn’t spot 55 Pegasi b directly—it’s no more possible to visualize a planet in the glare of its parent star from a distance of 50 light years than it is to see a moth fluttering near a streetlight from half a dozen blocks away. The greater the dimming, the bigger the diameter of the planet. It is the prototype for a class of planets called hot Jupiters. It was the first exoplanet to be discovered orbiting a main-sequence star, the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research. In the above picture of 51 Peg the planet is not visible - it can only be detected by noticing small changes in the star's motion. Use of this site constitutes acceptance of our.

There’s Ross 128 b, another Earth-sized world just 11 light years away, where surface temperatures are estimated to be a balmy 23º C (73º F). The transit method had turned up far more promising worlds than 55 Pegasi b. There’s Proxima Centauri b, an Earth-like planet just 4.2 light years away, which orbits its star in the “Goldilocks zone,” where temperatures are just right for liquid water to exist.

The greater the dimming, the bigger the diameter of the planet. It is the prototype for a class of planets called hot Jupiters. It was the first exoplanet to be discovered orbiting a main-sequence star, the Sun-like 51 Pegasi, and marked a breakthrough in astronomical research. In the above picture of 51 Peg the planet is not visible - it can only be detected by noticing small changes in the star's motion. Use of this site constitutes acceptance of our.
