Of all the moons in our solar system, the Martian moon of Phobos might be the most interesting. It’s not a near-perfect sphere like most of the moons we see, and it almost looks like an overgrown asteroid just kind of hanging out in orbit around the Red Planet. It’s also covered in craters and huge depressions, and long grooves that stretch almost its entire length.
Researchers have long wondered what caused those large valleys to form, and what kind of force it might have taken to blanket Phobos in such a strange pattern. Now, new research published in Planetary and Space Science may have finally solved that riddle, and it all comes down to some very large rocks.
