My brain immediately translated "Luna -> Terra -> Sol -> Astra" to "Moon -> Earth -> Sun -> Galaxy", an overall growing of size. While sure, "astra" doesn't directly translate to "galaxy", it's the base of the word "astronomical" and "astronomy".

I feel like people who don't get it immediately are just being deliberately obtuse.

"Ad Astra" my guy. "To The Stars"

Many of which are thiccer than our beta ass sun

Pretty badass name tbh
