It's already there in the Tourney rules, page 4, top right.

Yup now in addition to the Big One there is now the New Big One and the Not-as-Big One. And with the Small One there is now the Smaller One and Pebbles.

They also added a crescent and a (F-U) shaped rock into the middling pool but who would take medium sized asteroids now that there are 3 Big and 3 Small asteroids to take?
