Yes, I felt very heavy, because I was used to feeling weightless. Like suddenly I was carrying weights all over my body.

Yes - 12 humans have walked on the Moon. The Moon orbits Earth every month or so, and the Earth circles the Sun once per year.

Our Sun is typical of the septillion stars in the universe. It formed slowly, swirling gases pulled together by gravity.
