It's also the name of one of Saturn's moons and can be a Biblical name inspired by a female minister whom Apostle Paul trusted to deliver a letter to the Romans. Phoebe started gaining popularity as a girl's name in the U.S. at the start of the 21st century before cracking the top-200 for the first time ever in 2023.
