51 Eridani b is a planet that orbits 51 Eridani, in the constellation Eridanus.[1]
General information
51 Eridani b was announced August 2015, but was discovered in December 2014 using the Gemini Planet Imager, an international project led by the Kavli Institute for Particle Astrophysics and Cosmology. Its location is approximately 100 light years away, and it is approximately 20 million years old.[2]
Scientists estimate the mass to be twice that of Jupiter, and has the strongest methane signature of any Exoplanet.[3] The surface temperature is 650°C, which is substantially hotter than the minus 145°C surface temperature of Jupiter, the planet in our solar system of closest size.[4]
