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
2011 में पारगमन द्वारा खोजा गया पहला ग्रह (NASA एक्सोप्लैनेट आर्काइव)।
इसके ग्रह
Kepler-33 c — 3.2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 13 days; about 740 °C, hotter than boiling water; found in 2011 by transit.
Kepler-33 f — 4.5 times Earth's width, Neptune-sized; its year lasts 41 days; about 420 °C, hotter than boiling water; found in 2011 by transit.
Kepler-33 e — 4 times Earth's width, Neptune-sized; its year lasts 32 days; about 480 °C, hotter than boiling water; found in 2011 by transit.
Kepler-33 d — 5.4 times Earth's width, Neptune-sized; its year lasts 22 days; about 580 °C, hotter than boiling water; found in 2011 by transit.
Kepler-33 b — 1.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 6 days; about 1,100 °C, hot enough to melt rock; found in 2011 by transit.
