Hmm, what is the escape velocity of our solar system? Are the Voyagers going to fall back toward us some day?

[–] 9tr6gyp3@lemmy.world 19 points 3 days ago (2 children)

Depends in where you think the edge of the solar system is. If you think the edge of the solar system is where the Sun no longer has any gravitational pull, and another star's gravity takes over, then its going to take the voyagers another 40,000 years to escape our solar system.

To be pedantic, iirc there is no distance at which gravity stops having any pull

Well yes, I was wondering about the escape velocity not the escape distance.

The question is, are they actually going fast enough to cross that boundary and fall into another star's gravity well, or are they going to end up orbiting our star?

they’ll escape
