Thirty years ago, Voyager I was launched... it is now more than a hundred times farther away than the distance from the Earth to the Sun.
It is now more than one-half light-day away! At that rate, if it were going toward the nearest star, it is still only about 1/3,000th way there... meaning it would take nearly 100,000 years to arrive.
Voyager I is still functioning and is still sending back data! However, the power supply will run out in about 10 years.
