As of August 2007, Voyager 1 is approximately 9.7 billion miles from the sun. Voyager 2 is at approximately 7.8 billion miles. Voyager 1 is in the heliosheath, and Voyager 2 is approaching it.

In the next ten years, scientists expect the Voyagers to cross the heliopause, the edge of the bubble created by the sun's supersonic wind, and become the first craft to reach interstellar space.
