Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.
How it was found
First planet found in 2025, by transit and radial velocity (NASA Exoplanet Archive).
Its planets
TOI-6041 b — 4.6 times Earth's width, Neptune-sized; its year lasts 26 days; about 330 °C, hotter than boiling water; found in 2025 by transit.
TOI-6041 c — 11 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 88 days; about 130 °C, hotter than boiling water; found in 2025 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.
