The Moons of Mars
0.0July 14, 1970
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.
