Despite playing EVE for nearly 20 years, I never wondered this myself!

CCP Convict and I went asking around the CCP offices and found our answer from the one and only CCP Hellmar. The name “Tranquility” comes from the Sea of Tranquility on the moon - otherwise known as the first location visited by humanity on another celestial.

Thanks for the great question!
