I’m still loving this puzzle. The sun is finished, and Saturn is well on its way. I think I’ll do Jupiter next. Although the three biggest celestial bodies are all yellow, the sun pieces were easy to pick out, and mostly, I can also tell the difference between pieces of Saturn and pieces of Jupiter. Jupiter is next, I think.

In Roman mythology, Saturnus is the father of Jupiter. The Greek equivalent is Kronos, father of Zeus, and the planet was already known as Saturnus in ancient Rome. Somehow I never realized before that the habit of naming planets by Graeco-Roman deities actually goes back to ancient Greece. In China, the planets were named by elements, for example Mercury is the star of water, Mars the star of fire and Jupiter the star of wood. More about Chinese planet names.
