इसे कैसे खोजा गया
2011 में पारगमन और त्रिज्य वेग द्वारा खोजा गया पहला ग्रह (NASA एक्सोप्लैनेट आर्काइव)।
इसके ग्रह
Kepler-10 b — 1.5 times Earth's width, about Earth-sized — probably rocky; its year lasts 20 hours; about 1,900 °C, hot enough to melt rock; found in 2011 by transit.
Kepler-10 c — 2.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 45 days; about 310 °C, hotter than boiling water; found in 2011 by transit.
Kepler-10 d — 3.5 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 150 days; about 110 °C, hotter than boiling water; found in 2023 by radial velocity.
