Voyager 2 (Current Position)

The farthest human-made object still sending data home/Spacecraft

Voyager 2, launched in 1977, is the only spacecraft to have visited all four outer planets (Jupiter, Saturn, Uranus, Neptune). As of 2026, it is about 136 AU from Earth and still transmitting data using a 23-watt radio, about the power of a refrigerator light bulb. The signal takes over 18 hours to reach Earth. Its plutonium power source will keep it running until about 2025-2030, after which it will drift silently through interstellar space forever.
