Io is the innermost of the four Galilean moons of Jupiter. It is
named after the Greek mythological figure Io. Although the name "Io"
was suggested by Simon Marius soon after its discovery, this name and
the names of the other Galilean satellites fell into disfavor for a
considerable time, and were not revived in common use until the
mid-20th century. In much of the earlier astronomical literature, Io
is simply referred to by its Roman numeral designation as "Jupiter
I," or simply as "the first satellite of Jupiter."
