Solar wind data measured by VOYAGER 2 up through May 3, 2013

As of 8 March 2013, Voyager 2 was 9.437 billion miles from Earth (100.813 Astronomical Units from the Sun), well beyond the orbit of Pluto. Voyager 2 is leaving the solar system at 36,000 miles per hour, which is 3.2 AU per year, or 1 light year per 18,600 years.

On the same date, the light travel time from Voyager 2 to Earth was 14 hours, 4 minutes, 14 seconds. Data are returned from the spacecraft at 160 bits per second, using a transmitter with about 25 watts (!) of power.
