Voyager 1 is the farthest manmade object in the Solar System
Date: 11 Oct 2001 The outer boundary of the heliosphere, called the heliopause, is formed when the interstellar gases and magnetic fields exert more pressure then the gases and magnetic field associated with the Sun, forming the vast cavity of the heliosphere within. One of these distant spacecraft will most likely be the first spacecraft to go beyond the heliosphere and become the first interstellar traveller. Among the distant spacecraft heading for the boundary between the heliosphere and the local interstellar medium, Voyager 1 is the farthest manmade object in the Solar System. Image courtesy of NASA
