The Farthest Any Artificial Object Ever Went

Launched with great plans is the Voyager 1 in the last century

It visited the outer planets and sent us their info, and then, by their gravity also got an astonishing speed that allowed them to reach the escape velocity of the sun. Right now Voyager 1 has left the solar system officially and 150 AU away from Earth

It is still in contact and is expected to lose contact with us in the next 5 or 6 years... It will then keep drifting away in the dark empty space all alone

But, it has a Golden disc with sounds and images of Earth, with the hope that some aliens will find it one day & know about us :)
