MIT Space Plasma Group
Voyager Plasma Science Experiment
As of 26 December 2014, Voyager 2 was
9.998 billion miles from Earth
(106.5 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, 54 minutes, 31 seconds.
Data are returned from
the spacecraft at 160 bits per second, using a transmitter
with about 25 watts (!) of power.
