So, we had already established one word for a celestial body. As you’ll recall, that would be:
From there, ancient astronomers gave us:
affíëníel: (from traäffiën ashíël, “dancing star”), planet; and
chalíël: (from trachálporis ashíël, “circling star”), moon.
And slightly less ancient ones provided:
alélazik: (from traälél azik, “sky-rock”), asteroid
But just to ensure that some recent distinctions are captured:
traäffíënel chalíël: true-moon, moon of a planet; and
trachalíël chalíël: moonmoon, moon of a moon; and even the unlikely
traälélazik chalíël: moon of an asteroid.
