Voyager 1

The most distant human-made object in existence/Spacecraft

Launched in 1977, Voyager 1 has been traveling away from Earth for over 48 years and is now in interstellar space, more than 24 billion kilometers from home. It carries a Golden Record containing sounds and images of Earth for any extraterrestrial civilization that might find it. The probe's radio signal, traveling at the speed of light, takes over 22 hours to reach Earth, and its transmitter has less power than a refrigerator light bulb.
