The man-made object that is the furthest away from the Earth

Voyager 1 is the object made and sent by man that is the farthest away in space. In 2012, after a journey of 35 years, the space probe came out of the solar system (actually, beyond the influence of solar winds) to reach the interstellar medium. 

The probe has achieved on August 25, 2012, a travel of about 18 billion kilometers, which comes out of the influence of the sun (actually, beyond the influence of the solar wind). Nevertheless, it is still under the gravitational influence of the sun, for a few tens of thousands of years, but it is receding from us at a speed of approximately 57000 km/h. It will take another 40,000 years for Voyager 1 to reach the vicinity of another star, Gliese 445.

In early 2014, it was approaching 19 billions kilometers away from Earth. A signal now takes over 17 hours to travel the distance at the speed of light. Interactions with the probe so take nearly 35 hours between a sending message and the receiving of a response on Earth. 

Voyager 1 and its twin Voyager 2 each contain a disc with informations about the Earth, its people, and our solar system, sent through space towards any extraterrestrial civilizations. Among these details, photos, sounds, such as the sounds of a tractor and a chimpanzee or photos from a family dinner or the Grand Tetons' Mountains (which, by the way, means "big nipples" in french).
