Wie er entdeckt wurde

Erster Planet, entdeckt 2012 durch Transit und Transitzeitvariationen (NASA Exoplanet Archive).

Seine Planeten

Kepler-82 e — 2.5 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 6 days; about 650 °C, hotter than boiling water; found in 2014 by transit.
Kepler-82 f — 4.8 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 76 days; about 150 °C, hotter than boiling water; found in 2019 by transit timing variations.
Kepler-82 c — 5.3 times Earth's width, Neptune-sized; its year lasts 52 days; about 180 °C, hotter than boiling water; found in 2012 by transit.
Kepler-82 d — 1.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 2 days; about 980 °C, hotter than boiling water; found in 2014 by transit.
Kepler-82 b — 4.1 times Earth's width, Neptune-sized; its year lasts 26 days; about 290 °C, hotter than boiling water; found in 2012 by transit.

Woher das stammt

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.
