How far, from the Sun
About 95 light-years. To cross it:
- Light95 years
- Voyager 1's speed1.69 million years
- Driving at 100 km/h1.03 billion years
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 1999, by radial velocity (NASA Exoplanet Archive).
Its planets
- HD 75289 b — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 4 days; about 990 °C, hotter than boiling water; found in 1999 by radial velocity.

Where this comes from
- 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.
