Voyager 1's speed5.11 million years
Driving at 100 km/h3.1 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 2025, by radial velocity (NASA Exoplanet Archive).
Its planets
HIP 111909 b — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 490 days; about 160 °C, hotter than boiling water; found in 2025 by radial velocity.
HIP 111909 c — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 2 Earth years; about 85 °C, between freezing and boiling; found in 2025 by radial velocity.
