Voyager 1
Voyager 1 is the only man-made spacecraft to reach the farthest point in that time.
It was sent into space by the American space agency NASA on September 5, 1977. At that time, this spacecraft has reached a distance of 14 billion miles from the Earth with a speed of 38 thousand miles per hour.
If we send radio signals from Earth to Voyager One, they will reach it after 21 hours and 36 minutes.
