How far away is the Voyager 1 spacecraft?

In October 2026 Voyager 1 is about 25.7 billion km from Earth, roughly 172 times the Earth-Sun distance. A radio signal takes nearly 24 hours to reach it; on 18 November 2026 it passes one full light-day away. Launched in 1977, it is the most distant human-made object and still returns data from a handful of instruments.
