Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.
Facts
GJ 682 b has an equilibrium temperature between −50 and +50 °C.
How it was found
First planet found in 2014, by radial velocity (NASA Exoplanet Archive).
Its planets
GJ 682 b — 1.9 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 17 days; about 9 °C, between freezing and boiling; found in 2014 by radial velocity.
GJ 682 c — 2.9 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 57 days; about −83 °C, below freezing; found in 2014 by radial velocity.
