NASA scientists have discovered that mercury is shrinking!!!!!
it has shrunk 4 miles since it was formed 4 billion years ago. That means that it shrinks 1 mile every billion years!!!!!
it happened because the planet has a solid core but it once it had a liquid core like earth but it shrunk because the core turned solid because it got colder.
HI Jimmy,
ReplyDeleteI never knew that mercury is shrinking. I think that it is not cool because it will just do stuff to our solar system.
