It's Official: Voyager 2 Has Left Our Solar System And Is Sailing in Interstellar Space
Admin November 04, 2019
Voyager 2 has left the Solar System. After making a careful analysis of the data, scientists have confirmed it: like Voyager 1 before it, the little space probe is now out beyond the heliopause, and heading deeper into the vast unknown of interstellar space.
With five separate papers appearing today in Nature Astronomy, scientists confirm that Voyager 2 crossed into interstellar space on 5 November 2018, at a distance of 119 astronomical units (17.8 billion kilometres) from the Sun.
And, because Voyager 1's plasma instrument was broken when it crossed the heliopause six years earlier, it's the first time scientists have been able to study a full in-situ dataset of the plasma profile of this important boundary.
The two Voyager probes were launched all the way back in 1977 to study the outer Solar System. Voyager 2 was launched first, getting a head start of two weeks, but Voyager 1 was on a shorter trajectory through the Solar System.
