What Makes a Planet 'Habitable' or 'Uninhabitable'?

Imagine a planet like Earth, but if it were too close to the sun, it would be super hot, like a pizza in an oven. If it were too far away, it would be freezing, like living inside a freezer. A habitable planet is just right for life, like a warm room where you can grow food and stay comfortable.
