What's Carbon then? I haven't been paying much attention to Google but their naming has been confusing me.

Luna/Terra/Sol/Astra was a bit pretentious but at least the sizing makes sense. (I imagined the meeting... "Ok guys, we're getting mogged on naming... what's more epic than a Myth?" -"The SUN!")

Anthropic makes sense with the literary "scale" naming, mostly.

Is a Carbon bigger than an Argon though? Maybe it has to do with the atomic number?
