Thin disk

A thin disk is like a really flat pancake that spins around. Just like you spin a toy top, a thin disk can also spin. Think of a CD or a DVD, they're like thin disks that you put in a machine and they spin really fast. Scientists talk about thin disks when they're studying things like planets and galaxies. When they spin, they can create heat, light, or even gravity that can pull things towards them. So, thin disks are like big, flat, round things that can spin and influence other things around them.
