MIT Space Plasma Group Voyager Plasma Science Experiment

Plasma data measured by Voyager 2 up through 25 September 2024 (2024/269)

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 25 September 2024, Voyager 2 was approximately 12.776 billion miles from Earth (137.698 Astronomical Units from the Sun).

On the same date, the light travel time from Voyager 2 to Earth was approximately 19 hours, 3 minutes, 7 seconds. Data are returned from the spacecraft at 160 bits per second, using a transmitter with about 25 watts (!) of power.
