Voyager 1
The Voyager probes are floating indefinitely through space, reaching further than any other space mission.
  • Reddit users asked: If you were in space near the Voyager probes, would you be able to see them?
  • An astrophysicist told us that the sun would be bright enough for to see that far out in space.
  • It would be so bright, in fact, that you could probably read a book. 

When Voyager 1 launched in 1977, it began an indefinite journey into space, serving as an envoy for humankind. Today, it's the farthest human-made object from Earth, traveling over 15 billion miles from the sun in interstellar space.
