When pushing against something in space, do you have the same speed as the object moving away from you?

So since in space you have no weight but still have mass, do those physical calculations still apply when pushing an object that is heavier than you? I would imagine yes because everytime an astronaut pushed off the wall of the space shuttle the would change its course. I guess it's just getting the idea wrapped around my head with a little explination. Thanks!

You have the same momentum, not the same speed. If you pushed off of an object of the same mass as yourself, you'd have the same speed, an object with less mass would be moving faster than you, and a heavier object would be moving slower.
