How far can you jump in space?

Answer 1

That question has no definite answer, because there's no inherent limit.

If you jump in space, you just keep going, until you bump into something

that stops you.

Answer 2

In space, there is no atmosphere to provide resistance, so an object can technically travel infinite distances. However, in terms of human capability, the distance you can jump in space would depend on your initial velocity and how you apply force.
