Io (pronounced EYE-oh) is the inner most moon of the planet Jupiter and the fourth-largest moon in our Solar System. Discovered in 1610 by Galileo Galilei, the four Galilean moons (Io, Europa, Ganymede and Callisto) were the first moons outside of our Earth Moon to be observed around a planet. Galileo named the four moons after mythological lovers of Zeus, the Greek equivalent of Jupiter.
When the Voyager spacecrafts journeyed past Jupiter in 1979 they sent back amazing photographs documenting the volcanic surface of Io. Another first. Prior to this discovery, volcanic activity within our solar system had only been observed on Earth.
Alice io was named by her father, who has a love of astronomy and interesting names.
(Note: Although Io is a proper noun, Alice io chooses to write it lower case to eliminate confusion with the letter “L” or “J” in some typefaces.)
