The Atlas of Moons is insanely informative for us lay-people but extra gorgeous and much more entertaining to digest on an iPhone.
Among the eight major planets, Earth is the only one with a single moon. Over millennia, our planet’s celestial companion has assumed many roles: Its shifting, glowing face has inspired myths and legends; its cratered surface continues to be a prime destination for robotic and human explorers; and its gravitational heft and silvery light tangibly affect life on this planet.
So National Geographic of course tows the 8 planet party line, but they sure do spend a lot of ink talking about my 9th planet.
