Titanic Terminology, Superfluous linguistic inquiry Options

[David]

What is the accepted adjective used to mean "of or related to the moon Titan", comparable to (e.g.) Solar, Lunar, Martian, Jovian, Saturnian?
On the model of the last three, one would conclude "Titanian" -- but that would leave no appropriate adjective for the Uranian moon Titania.
Checking my Latin and Greek dictionary, I find the following options:
1) Titaniac (Lat. Titaniacus)
2) Titanid (Lat. Titanis)
3) Titanic (Gr. Titanikos)

Are any of these used? Or something else. I'd just like to be able to correctly refer to "The T______ hills/lakes/rivers/craters/atmosphere (etc.)" without having to say "of Titan" all the time.

The Titan hills

The titan seas

I think Titan does as noun and adjective to be honest

But I'm sure some IAU bod knows the real story
