You don't even need to change the spelling, just pronounce it a way that better resembles the underlying Greek. Problem is, no English-speaker needs to think about pronunciation for the other planets because the latin is just pronounced phonetically.

It's weird that it's the one Greek-named planet. If we're changing things up, it should just be Caelus to match the others.
