How close will it pass to us?

More to the point, what is the escape velocity of the Milky Way in our vicinity?

It is moving away from us

About 550 km/s

But it wasn’t ejected near us

> About 550 km/s

That’s fast. Speed of sun around Milky way is 230 km/s. So it makes sense that we would need to double that to get out of the galaxy. Thanks.
