Phobos orbits so close that it rises and sets twice each day, while Deimos drifts farther away. One day, Phobos may even break apart, forming a ring around Mars. #SpaceX #space #NASA | Moon Watchers Club | Facebook

It's actually pure coincidence that our Sun and Moon appear to be roughly the same size in the sky - the Sun is around 400x larger than the Moon, but also around 400x more distant. Without this odd coincidence, we wouldn't get the "total" eclipses that we get here on Earth. | IFLScience | Facebook

They are small, oddly shaped, and look more like captured asteroids than perfect round moons. Scientists believe Mars’ gravity pulled them in long ago. Their strange shapes and mysterious origins make them some of the most fascinating objects orbiting a planet in our Solar System.  #space #SpaceX #NASA #fblifestyle | Nighttime.Adventures | Facebook
