Voyager 1
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 currently in the constellation of Ophiucus. The current Right Ascension of Voyager 1 is 17h 14m 43s and the Declination is +12° 25’ 28” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ).

Voyager 1 Distance from Earth
The distance of Voyager 1 from Earth is currently 23,830,605,336 kilometers, equivalent to 159.297758 Astronomical Units. Light takes 22 hours, 4 minutes and 50.3431 seconds to travel from Voyager 1 and arrive to us.
The following chart shows the distance of Voyager 1 from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of Voyager 1 from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Voyager 1 to Earth
Between 1 January 2013 and 30 December 2099, the closest approach of Voyager 1 to Earth happens on Mon Apr 22 2013 at a distance of 123.348498 Astronomical Units, or 18,452,672,648 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Visualization of Voyager 1 Orbit
This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Voyager 1 with respect of the Sun and the orbits of the major planets. The position of Voyager 1 and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!
