How far, from the Sun

About 309 light-years. To cross it:

• Light309 years
• Voyager 1's speed5.48 million years
• Driving at 100 km/h3.33 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 2020, by imaging (NASA Exoplanet Archive).

Its planets

• TYC 8998-760-1 c — 12 times Earth's width, a giant, Jupiter-sized or more; about 970 °C, hotter than boiling water; found in 2020 by imaging.
• TYC 8998-760-1 b — 21 times Earth's width, a giant, Jupiter-sized or more; about 2,400 °C, hot enough to melt rock; found in 2020 by imaging.

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.
