There are currently 5 badge tiers, besides challenge patches, so there isn’t enough for recognizable badges of matching spots. I’d like to add 5 more types, Asteroid, Jupiter, Solar System, Galaxy, And Universal. This will extend how much badges you can earn.
So here are all of these badges

Asteroids: Asteroid Badges Are Partially Common. They Represent A Concept of Education.

Jupiter: Jupiter Badges Are Very Rare. They Represent Hard Work And Time

Solar System Badges: Solar System Badges Are Almost Legendary And Some Aren’t Known. They Are Very Rare Badges, Almost As Rare As Black Hole Badges.

Galaxy Badges: Galaxy Badges Are Mythical. Galaxy Badges Are Unknown And Requires Almost All Dedication.

Universal Badges: Universal Badges Are Celestial And Unknown. They Are The Rarest And Most Impossible Badges. They’re So Unpleasant That No Sane Person Alive Will Ever Think Of Getting Any Of These Badges.

I’d also add new challenge patch badges, for veterans. They are meant to look retired, so no modern player like me can get these badges unless one of the badges shown above.
