So, the gravity on the moon is (80 divided by 14) six times as weak. This means the moon actually has 80 times less mass than Earth. If that same mass was squeezed down to the size of a village, it’d become a black hole, and we’d all be sucked into it.īut the moon is made of similar stuff as the outer bits of the Earth, which are less dense and float on top of the heavier core in the middle, like oil floats on top of water.Ĭurious Kids: what would happen if the Earth's core went cold? But if it had the same mass, then the moon’s gravity would be about 14 times stronger than Earth’s and you’d hardly be able to jump at all. The moon is just over a quarter of the size of the Earth. Perhaps it’s not surprising, then, that the moon orbits around the Earth, since our planet is so much bigger.īut wait – it’s not just size that matters, mass does too. If you have a question you’d like an expert to answer, send it to We won’t be able to answer every question, but we’ll do our very best.Īnything with mass changes space in this way. ![]() Curious Kids is a series by The Conversation, which gives children the chance to have their questions about the world answered by experts. ![]()
