Ses planètes

Kepler-296 d — 2.1 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 20 days; about 130 °C, hotter than boiling water; found in 2014 by transit.
Kepler-296 b — 1.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 11 days; about 220 °C, hotter than boiling water; found in 2014 by transit.
Kepler-296 c — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 6 days; about 330 °C, hotter than boiling water; found in 2014 by transit.
Kepler-296 f — 1.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 63 days; about 1 °C, between freezing and boiling; found in 2014 by transit.
Kepler-296 e — 1.5 times Earth's width, about Earth-sized — probably rocky; its year lasts 34 days; about 64 °C, between freezing and boiling; found in 2014 by transit.
