Name them after Norse gods:
Baldr,
Bragi,
Búri,
Forseti,
Heimdall,
Hermóðr (my personal favorite),
Höðr,
Kvasir,
Loki,
Odin,
Ríg,
Thor, and
Tyr. We all learned the all important Greek/Roman mythos from the heavens in school, maybe it's time to learn about different mythology from the cosmos. The names could be applied appropriately (Odin or Thor for the big planet, Loki for a small planet with a mischevious orbit....etc.).
