Come è stato scoperto

Primo pianeta scoperto nel 2014 con le variazioni dei tempi di transito, il transito e la velocità radiale (NASA Exoplanet Archive).

I suoi pianeti

Kepler-139 f — 6.7 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 360 days; found in 2025 by transit timing variations.
Kepler-139 c — 3.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 160 days; about 77 °C, between freezing and boiling; found in 2014 by transit.
Kepler-139 e — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 6 Earth years; about −120 °C, below freezing; found in 2023 by radial velocity.
Kepler-139 b — 2.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 16 days; about 480 °C, hotter than boiling water; found in 2014 by transit.
Kepler-139 d — 1.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 7 days; about 700 °C, hotter than boiling water; found in 2023 by transit.
