It's incredible to think of a planet shriveling up like that. Imagine how far it will go. Does anyone know why it's shrinking?

"The innermost world has shrunk as it has cooled over time, its surface cracking and wrinkling in the process." from the BBC

The amount of cooling/shrinking depends on the composition of the planet and is being used to estimate the radius of its core.
