1975 despite calls to give it a proper name shortly after the discovery of
it and Elara a month later. It was the 6th moon to be discovered around
Jupiter so was known as Jupiter VI (6), but the traditional naming system
was getting confusing. Jupiter V (5) was closer to Jupiter than Jupiter I
(1), II (2), III (3) and IV (4). Jupiter VI (6) came after Jupiter IV (4)
in its orbit around Jupiter. Between 1955 and 1975, it was sometimes known
as Hestia (a Greek goddess) |

previously known as Jupiter VII (7) or Hera (between 1955 and 1975) |
