Venetia Burney suggested the name Pluto after the Roman god of the Underworld after her grandpa informed her about the newly found planet. Pluto the planet, like the God, sat in the furthest ends of the solar system, thus it felt appropriate. Her grandpa was taken with the name and proposed it to a friend, who happened to be an Oxford University astronomy professor. Pluto piqued the interest of astronomers since the first two letters of the name are Percival Lowell's initials.
