Come è stato scoperto

Primo pianeta scoperto nel 2012 con il transito (NASA Exoplanet Archive).

I suoi pianeti

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.
