Why do untethered objects float away in Space?
Question Date: 2020-05-29
Answer 1:

On Earth, gravity holds things to the ground, and the ground creates friction that prevents things on the ground from moving. Space has no ground, and so no friction, so even the slightest difference in speeds between objects will cause them to drift apart.
