Phobos & Deimos:  Two “misplaced” asteroids?
						Grooves seem related to the large crater called “Stickney”
			• Phobos and Diemos are small (~25 km and ~15 km diam.) moons of Mars • Look like captured asteroids rather than moons formed in place • Are “C” class – i.e. dark “Carbonaceous” type “asteroids”
