MIT Space Plasma Group
Voyager Plasma Science Experiment
Voyager 2 left our heliosphere and entered the local interstellar medium
in 2018 and continues to travel outward at 36,000 miles per
hour (which is 3.2 AU per year, or 1 light year per 18,600 years).
As of 24 November 2021, Voyager 2 was approximately
12.012 billion miles from Earth
(128.704 Astronomical Units from the Sun).
On the same date, the light travel time from Voyager 2 to
Earth was approximately 17 hours, 54 minutes, 43 seconds.
Data are returned from
the spacecraft at 160 bits per second, using a transmitter
with about 25 watts (!) of power.
