Did you know that Phobos, one of Mars' moons, is actually slowly spiraling inward towards the planet? Since Phobos is much smaller than Earth's Moon, the eclipse it creates is not as dramatic.

However, what makes it interesting is the frequency of these events. Phobos orbits Mars much faster than the Moon orbits Eart
