642000 km from Jupiter on 1979 Jul 10.
101000 km from Saturn on 1981 Aug 26.14.
80000 km from Uranus on 1986 Jan 24.75.
4900 km from Neptune on 1989 Aug 25.16.
Flyby of Saturn moons Enceladus (at 86754 km) and Tethys (at 92474 km) on Aug 26, 1981 (03:45? and 06:12? UT).
Entered Neptune's gravitational sphere of influence on about July 4, 1989.
Left Solar system in direction of Alpha Canis Major, reaching Sirius after 358000 years.
In 1993 at 36 AU from Sun at 3.1 AU/year.
In 2002 March at 67 AU from Sun at 3.3 AU/year.
On August 30, 2007, Voyager 2 passed the termination shock into the heliosheath, approximately 1 billion miles (1.6 billion km) closer to the Sun
than Voyager 1 did. This is due to the local interstellar magnetic field of deep space. The southern hemisphere of the Solar System's heliosphere is
being pushed in.
On Jan 1, 2010 Voyager 2 was 91.0 AU from the Sun.
As of April 13, 2010 Voyager 2 was at a distance of around 91.898 AU (13.747 billion km or 0.001443 light years) from the Sun, deep in the
scattered disc, and traveling outward at roughly 3.264 AU per year. It is more than twice as far from the Sun as Pluto, and far beyond the perihelion
of 90377 Sedna, but not yet beyond the outer limits of the orbit of the dwarf planet Eris.
Voyager 2 is not headed toward any particular star. If left alone, it should pass by star Sirius, which is currently about 2.6 parsecs from the Sun
and moving diagonally towards the Sun, at a distance of 1.32 parsecs (4.3 ly, 25 trillion mi) in about 296,000 years.
Voyager 2 is expected to keep transmitting weak radio messages until at least 2025, over 48 years since it was launched.
