Come è stato scoperto

Primo pianeta scoperto nel 2014 con il transito (NASA Exoplanet Archive).

I suoi pianeti

Kepler-122 e — 2.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 38 days; about 350 °C, hotter than boiling water; found in 2014 by transit.
Kepler-122 c — 5.9 times Earth's width, Neptune-sized; its year lasts 12 days; about 620 °C, hotter than boiling water; found in 2014 by transit.
Kepler-122 f — 1.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 56 days; about 270 °C, hotter than boiling water; found in 2014 by transit.
Kepler-122 d — 2.2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 22 days; about 470 °C, hotter than boiling water; found in 2014 by transit.
Kepler-122 b — 2.3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 6 days; about 890 °C, hotter than boiling water; found in 2014 by transit.

NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
