Wie er entdeckt wurde

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

Seine Planeten

Kepler-49 b — 2.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 7 days; about 240 °C, hotter than boiling water; found in 2012 by transit.
Kepler-49 c — 2.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 11 days; about 170 °C, hotter than boiling water; found in 2012 by transit.
Kepler-49 d — 1.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 3 days; about 440 °C, hotter than boiling water; found in 2014 by transit.
Kepler-49 e — 1.6 times Earth's width, about Earth-sized — probably rocky; its year lasts 19 days; about 98 °C, between freezing and boiling; found in 2014 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.
