How it was found
First planet found in 2014, by transit (NASA Exoplanet Archive).
Its planets
Kepler-210 b — 2.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 2 days; about 460 °C, hotter than boiling water; found in 2014 by transit.
Kepler-210 c — 3.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 8 days; about 220 °C, hotter than boiling water; found in 2014 by transit.
