The Naming of Ganymede

The moon Ganymede was discovered in 1610 by Galileo Galilei, along with three other moons of Jupiter: Io, Europa, and Callisto. At the time, the moons were referred to as the "Galilean satellites" in honor of their discoverer. However, in the mid-1800s, the naming system was changed, and the moons were given names from Greek and Roman mythology.

Ganymede was chosen as the name for the largest moon of Jupiter because of its association with beauty and youth. In Greek mythology, Ganymede was known for his exceptional beauty, and the moon was seen as a symbol of that beauty.
