Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.
Facts
GJ 1002 b has an equilibrium temperature between −50 and +50 °C.
How it was found
First planet found in 2022, by radial velocity (NASA Exoplanet Archive).
Its planets
GJ 1002 b — 1 times Earth's width (estimated from its mass, not measured), about Earth-sized — probably rocky; its year lasts 10 days; about −42 °C, below freezing; found in 2022 by radial velocity.
GJ 1002 c — 1.1 times Earth's width (estimated from its mass, not measured), about Earth-sized — probably rocky; its year lasts 21 days; about −91 °C, below freezing; found in 2022 by radial velocity.
NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
