The Solar System's Major Moons The Solar System contains 18 or 19 natural satellites of planets that are large enough for self-gravity to make them round. (Why the uncertain number? Neptune’s moon Proteus is on the edge.) They are shown here to scale with each other. Two of them are larger than Mercury; seven are larger than Pluto and Eris. If they were not orbiting planets, many of these worlds would be called “planets,” and scientists who study them are called “planetary scientists.”

Really nice montages! But why use a black & white photo of our moon, while all the other moons are in color?

It is a color photo of the Moon. Perhaps it should be a little browner, but if we're really getting persnickety then it should also be much darker than anything on there except the dark side of Iapetus.
