How far, from the Sun

About 997 light-years. To cross it:

• Light997 years
• Voyager 1's speed17.7 million years
• Driving at 100 km/h10.8 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 2009, by eclipse timing variations (NASA Exoplanet Archive).

Its planets

• DP Leo b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 28 Earth years; about −250 °C, below freezing; found in 2009 by eclipse timing variations.

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.
