FIND YOUR "WEIGH"
Here's a tricky question:
Q: There is gravity in space. Yes or No?
A: Yes. But what about all those astronauts floating around? Surely that means there's no gravity in space. You're right about that
itself has no gravity. But stars, moons, and other planets do. In fact, they have more or less gravity than Earth, depending on their mass. You wouldn't be weightless if you were on another planet, you'd just weigh more or less. See for yourself! Figure out how much you would weigh on each of the planets. Graph your space weights. On which planets would you be lightest? Why?
