Think about it. gravity.
If it was simply some boulder loose on the surface of Phobos, id doubt it would just stay there, since Phobos is tiny, doesnt have much gravity to it.
I dont see an obeslisk shape though, bit it is very interesting. Whatever it is, it seems to be wedged into the rock. Phobos is an asteroid that
became a moon. It has no atmosphere, and very weak gravity.
Good find. Would really like to see more theories on it.
