How far, from the Sun

About 1,100 light-years. To cross it:

• Light1,100 years
• Voyager 1's speed19.6 million years
• Driving at 100 km/h11.9 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 2014, by transit (NASA Exoplanet Archive).

Its planets

• Kepler-108 c — 8.2 times Earth's width, Neptune-sized; its year lasts 190 days; about 150 °C, hotter than boiling water; found in 2014 by transit.
• Kepler-108 b — 8.7 times Earth's width, Neptune-sized; its year lasts 49 days; about 400 °C, hotter than boiling water; found in 2014 by transit.

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.
