Yes! Anything that has mass has gravity. The more mass something has (the bigger it is), then the more gravity it will have. So everything around us (including all the planets) have gravity! Even people have gravity...it's just that people are so small that there's not enough gravity to matter. Even the biggest building on the Earth is too small to have enough gravity for you to notice it. But since planets are /really/ big, they have enough gravity to hold things down.
