Voyager 1 is a space probe launched by NASA on September 5, 1977, to study the outer Solar System and beyond. It is currently the most distant human-made object from Earth, having traveled over 14 billion miles (23 billion kilometers) from the Sun. Voyager 1's mission has included flybys of Jupiter and Saturn, with the goal of studying their moons, rings, and magnetic fields. The probe is now traveling through the heliosheath, the outermost layer of the Sun's heliosphere, and is expected to enter interstellar space in the coming years. Voyager 1 carries a golden record that contains sounds and images selected to portray the diversity of life and culture on Earth, in the event that it is ever encountered by extraterrestrial life.

Voyager 1 is in the constellation of Ophiuchus, at a distance of 24,896,852,686.0 kilometers from Earth. The current Right Ascension is 17h 17m 42s and the Declination is +12° 04’ 55” (apparent coordinates).
