Neptuno

This name derives from the Latin “Neptūnus,” perhaps from the Latin “nō > natō,” meaning “to swim” or from “nauta,” borrowed from Ancient Greek “naútēs (ναύτης),” meaning “sailor, seaman, companion at sea.” 1) Neptune was the Roman god of water and the sea in Roman mythology and religion. He is the counterpart of the Greek god Poseidon. In the Greek-influenced tradition, Neptune was the brother of Jupiter and Pluto. 2) Neptune is the eighth and farthest known planet from the Sun in the Solar System. In the Solar System, it is the fourth-largest planet by diameter, the third-most-massive planet, and the densest giant planet. 3) Nettuno is a town and comune of the Metropolitan City of Rome in the Lazio region of central Italy, 60 kilometers (37 miles) south of Rome. Its name is perhaps in honor of the Roman god Neptune.
