what would earth c's constellations/zodiac signs be like?

to clarify, i have read only a bit of the epilogues and nothing of beyond canon yet. but i've been wondering this, and i feel like it's inconsequential enough that it wouldn't spoil any of it for me, should i know.

does any of the dubiously canon content address this? since the genesis frog was created in the alpha kids' session, i'd assume there'd be 4 constellations, or 8 including the beta kids? since the b2 session is for the beta kids to win? does it count the trolls who're on earth c? like, is there cancer, alongside "john, the prankster" or whatever, but not scorpio?
