Fatos

Kepler-454 c tem uma temperatura de equilíbrio entre −50 e +50 °C.

Como foi descoberto

Primeiro planeta descoberto em 2015 por velocidade radial e trânsito (NASA Exoplanet Archive).

Seus planetas

Kepler-454 d — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 11 Earth years; about −150 °C, below freezing; found in 2023 by radial velocity.
Kepler-454 b — 2.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 11 days; about 640 °C, hotter than boiling water; found in 2015 by transit.
Kepler-454 c — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 520 days; about −23 °C, below freezing; found in 2015 by radial velocity.
