The lunar crater Fontenelle, located in the northern part of the moon.
Why is it called “Fontenelle”? Well, it’s named after this guy, who in 1683 wrote a work about the plurality of worlds/infinite nature of the universe (Entretiens sur la pluralité des mondes) that played an extremely important role in popularizing the concept among laypeople. His predecessors in that field tended to get executed and imprisoned for their thoughts, so it was good that he stayed alive & escaped being condemned by the Pope or something.
Oh, and he didn’t just barely stay alive, he REALLY stayed alive, dying only one month before his 100th birthday. The secret to his longevity? He claimed it was a result of eating a lot of strawberries. Try that method at your own risk.
