I’ve observed the same confusion when attempting to determine the Snapchat Solar System order and its connection to the BSF planets. That’s actually a great question. It’s hard to keep track of what’s new because some of the information online is either out of date or mixed with planets only used for events. If you could share a verified list or perhaps an updated guide, it would be greatly appreciated. I’d also like to know if there is a visible indicator in the game that tells me which planets have been unlocked.
