The ruler of Pisces is Neptune (a symbol of superb imagination)
Neptune is the eighth planet and the fourth largest celestial body (diameter) orbiting the sun. Neptune is smaller in diameter than Uranus, but larger in mass than Uranus. Neptune's mass is about 17 times that of the earth, while Uranus, a twin star, is about 14 times that of the earth because of its low density. Neptune is Neptune in Roman mythology. Because Neptune is a sea god, Chinese is translated into Neptune. The symbol of astronomy is the trident used by Poseidon in Greek mythology.
