How far, from the Sun

About 28,100 light-years. To cross it:

• Light28,100 years
• Voyager 1's speed498 million years
• Driving at 100 km/h303 billion years

Voyager 1 at the speed it moved outward over the year to 2026-10-25 (JPL Horizons). Driving: nonstop, never refuelling.

Facts

• In 1994 it became the first object in the Milky Way seen to throw out jets with apparent faster-than-light motion — an illusion of geometry.
• Its black hole is about 12 times the Sun's mass (Reid et al. 2014).
