I love the details in this film. Things like the winged people flying on Titan, possible due to its dense atmosphere. There are things on these other worlds that we could never experience here.
Even the title has multiple meanings to it:
In ancient times, astronomers noted how certain lights moved across the sky in relation to the other stars. Ancient Greeks called these lights πλάνητες ἀστέρες (planetes asteres, "wandering stars") or simply πλανῆται (planētai, "wanderers"), from which today's word "planet" was derived.
