Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.
Facts
Kepler-62 e has an equilibrium temperature between −50 and +50 °C.
How it was found
First planet found in 2013, by transit (NASA Exoplanet Archive).
Its planets
Kepler-62 b — 1.3 times Earth's width, about Earth-sized — probably rocky; its year lasts 6 days; about 480 °C, hotter than boiling water; found in 2013 by transit.
Kepler-62 d — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 18 days; about 240 °C, hotter than boiling water; found in 2013 by transit.
Kepler-62 e — 1.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 120 days; about −3 °C, below freezing; found in 2013 by transit.
Kepler-62 f — 1.4 times Earth's width, about Earth-sized — probably rocky; its year lasts 270 days; about −65 °C, below freezing; found in 2013 by transit.
Kepler-62 c — 0.5 times Earth's width, smaller than the Earth; its year lasts 12 days; about 310 °C, hotter than boiling water; found in 2013 by transit.
