Cómo se descubrió

Primer planeta descubierto en 2013, por variaciones en el tiempo de tránsito, tránsito y velocidad radial (NASA Exoplanet Archive).

Sus planetas

KOI-142 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 22 days; about 360 °C, hotter than boiling water; found in 2013 by transit timing variations.
KOI-142 b — 3.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 11 days; about 490 °C, hotter than boiling water; found in 2013 by transit.
Kepler-88 d — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 4 Earth years; about −110 °C, below freezing; found in 2020 by radial velocity.
