The right to name the new object belonged to the Lowell Observatory and its director, Vesto Melvin Slipher. Tombaugh urged Slipher to suggest a name quickly for the new object before someone else did.[7] Name suggestions poured in from all over the world. Constance Lowell, Percival Lowell's widow, proposed Zeus, then Lowell, and finally her own first name, none of which met with any enthusiasm. Mythological names, such as Cronus and Minerva, were high on a list of considered names.[9]
The name Pluto was first suggested by Venetia Burney (later Venetia Phair), an eleven-year-old girl from Oxford, England.[10] Venetia, who was interested in Classical mythology as well as astronomy, suggested the name, the Roman equivalent of Hades, in a conversation to her grandfather Falconer Madan, a former librarian of Oxford University's Bodleian Library.[11] Madan passed the suggestion to Professor Herbert Hall Turner, Turner then cabled the suggestion to colleagues in America. After favourable consideration which was almost unanimous,[citation needed] the name Pluto was officially adopted and an announcement made on May 1, 1930.[10] Upon the announcement, Madan gave Venetia five pounds as a reward.[10]
The name retained for the object is that of the Roman god Pluto, and it is also intended to evoke the initials of the astronomer Percival Lowell. In the Chinese, Japanese, and Korean languages, the name was translated as death king star (冥王星), suggested by Houei Nojiri in 1930. In Vietnamese it is named after Yama (Sao Diêm Vương), the Guardian of Hell in Buddhist mythology. Yama (Devanāgarī यम) is also used in India, as it is the deity of Hell in Hindu mythologies.
