행성

Kepler-289 e — 2.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 330 days; about 13 °C, between freezing and boiling; found in 2025 by transit.
Kepler-289 b — 2.5 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 35 days; about 330 °C, hotter than boiling water; found in 2014 by transit.
Kepler-289 d — 3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 66 days; about 230 °C, hotter than boiling water; found in 2014 by transit.
Kepler-289 c — 11 times Earth's width, a giant, Jupiter-sized or more; its year lasts 130 days; about 120 °C, hotter than boiling water; found in 2014 by transit.
