A few items FYI:
Saturn has a moon that looks like the Death Star.
That moon has a smooth surface with an ocean underneath.
The ocean is really new.
It exists because of squeezing.
The moon may be very new as well, or possibly the other moons that squeeze it.
What a wonderful world. https://www.scientificamerican.com/article/saturns-death-star-moon-may-hide-a-massive-shockingly-young-ocean/
