The Voyager-1 is the most distant man-made object, and by the way, on board is a golden disc record. The mission was launched in 1977, passed the planets Saturn, Uranus, Neptune and has been in interstellar space for 20cc on the way to the nearest star AC + 79 3888, better known as Gliese 445 in the constellation Giraffe at a distance of 1.6 light-years, for which he will need 40,000 years of travel time. The fuel will last for 40 years, but the radionuclide batteries will probably not be able to deliver enough energy in 2025 to be able to transmit any further measurement data.
