Jupiter is also used as a feminine name in Roman Mythology and Greek Mythology. However, it's more common for males. So, I think that the "Gender" of this name should be updated from "Masculine" to "Masculine & Feminine". A known female bearer of this name is Jupiter, a Team Galactic Admin in Pokémon Diamond, Pearl, Platinum, Brilliant Diamond, & Shining Pearl.

Jupiter Jones was the lead investigator in the book series "Alfred Hitchcock and the Three Investigators". Robert Arthur Jr. was the author and I am unclear just how Hitchcock was involved. The books were similar to The Hardy Boys, but in my opinion, better written. As this was my introduction to the name I associate cleverness with the name.
