वॉयजर 1 उस गति से जिससे यह 2026-10-25 तक के वर्ष में बाहर की ओर बढ़ा (JPL Horizons)। ड्राइविंग: बिना रुके, कभी ईंधन भरे बिना।
इसे कैसे खोजा गया
2012 में पारगमन द्वारा खोजा गया पहला ग्रह (NASA एक्सोप्लैनेट आर्काइव)।
इसके ग्रह
Kepler-55 b — 2.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 28 days; about 130 °C, hotter than boiling water; found in 2012 by transit.
Kepler-55 e — 1.6 times Earth's width, about Earth-sized — probably rocky; its year lasts 5 days; about 460 °C, hotter than boiling water; found in 2014 by transit.
Kepler-55 d — 1.6 times Earth's width, about Earth-sized — probably rocky; its year lasts 2 days; about 660 °C, hotter than boiling water; found in 2014 by transit.
Kepler-55 c — 2.2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 42 days; about 76 °C, between freezing and boiling; found in 2012 by transit.
Kepler-55 f — 1.6 times Earth's width, about Earth-sized — probably rocky; its year lasts 10 days; about 290 °C, hotter than boiling water; found in 2014 by transit.
