51 Eridani b

(51 Eri b)
(Jupiter-like planet discovered in 2015)

51 Eridani b (aka 51 Eri b) is an extra-solar planet discovered through direct imaging in 2014 with the Gemini Planet Imager. It orbits about 14 AU from F-type star, 51 Eridani. As a directly-imaged object, data from observing it is useful in modeling apparently-similar objects orbiting closer to their hosts. Its effective temperature derived through spectroscopy is 700 K. The star's age is estimated as around 20 million years, suggesting a similar age for the planet, constraining it to be no more than that. Models of such a planet that include clouds in its atmosphere suggest a mass of roughly 2 Jupiter masses is plausible.
