One Of Mars' Moons Is Literally Pulling Itself To Pieces

One of Mars' Moons Is Literally Pulling Itself to Pieces

Mars’ moon Phobos is a strange, cratered, misshaped moon — and it’s pulling itself to pieces from the inside out.

We already knew that Phobos appeared to be falling apart for some time now. This new 3D-model from NASA, though, gives us a much better look at the forces that are causing the collapse.

Because Phobos is so close to the Martian surface, it’s subject to a much stronger than usual gravitational pull. The result of that pull can be seen up close in what researchers are calling “stretch marks” covering the moon:

NASA estimates that Phobos will have completely broken up within 30-50 million years.
