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।
तथ्य
केपलर-445 d का साम्य तापमान −50 से +50 °C के बीच है।
इसे कैसे खोजा गया
2015 में पारगमन द्वारा खोजा गया पहला ग्रह (NASA एक्सोप्लैनेट आर्काइव)।
इसके ग्रह
Kepler-445 b — 1.6 times Earth's width, about Earth-sized — probably rocky; its year lasts 3 days; about 130 °C, hotter than boiling water; found in 2015 by transit.
Kepler-445 c — 2.5 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 5 days; about 68 °C, between freezing and boiling; found in 2015 by transit.
Kepler-445 d — 1.3 times Earth's width, about Earth-sized — probably rocky; its year lasts 8 days; about 32 °C, between freezing and boiling; found in 2015 by transit.
