A graphic shows the positions of the outer planets - Jupiter, Saturn, Uranus, and Neptune- in relation to five distant spacecraft. They are Voyager 1, Voyager 2, Pioneer 10, Pioneer 11, and New Horizons

Interstellar Spacecraft

This graphic shows the relative positions of NASA’s most distant spacecraft in early 2011, looking at the solar system from the side. Voyager 1 is the most distant spacecraft, about 17.5 billion kilometers (10.9 billion miles) away from the sun at a northward angle. Pioneer 10, the next most distant, is about 15.4 billion kilometers (9.6 billion miles) away from the sun on the opposite side of the solar system. Voyager 2 is about 14.2 billion kilometers (8.8 billion miles) away from the sun on a southward trajectory, on the same side of the solar system as Voyager 1. Pioneer 11 is about 12.4 billion kilometers (7.8 billion miles) away from the Sun. New Horizons is about 3 billion kilometers (2 billion miles) away from the sun, on its way to Pluto.
