How far, from the Sun
135 light-years. To cross it:
- Light135 years
- Voyager 1's speed2.4 million years
- Driving at 100 km/h1.46 billion years
Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.
Facts
- It is thought to be the product of two white dwarfs merging (Caiazzo et al. 2021, Nature 595, 39).
- Its distance comes from a Gaia parallax: the tiny yearly shift in its position as the Earth circles the Sun.
