1970-07-140.0 rating
The two tiny Moons of Mars, Phobos and Deimos, are unlike any other astronomical bodies known to us. Too small to be satellites like our Moon - are they asteroids or minor planets? Patrick Moore examines photographs from the Mars probe Mariner 7 and talks about the unique circumstances of these two astronomical dwarfs.
