Geocache Description:

Homage to astronomically great Northern CA Solar System by TeamJiffy. No comet code.

Ganymede is the largest moon of our solar system, with a diameter of 3300 miles (compare Earth at 8000 miles).

It was first seen by Galileo about 400 years ago, through the then newly invented telescope. He observed Jupiter against a background of several close at hand, uniquely lined up stars. He expected Jupiter to revolve through and leave the star pattern the next night. Instead, they still stuck with Jupiter, yet in a different linear pattern. After several nights of this, Galileo realized they were moons orbiting another celestial body.

Until that day, the Earth was the only known divine body, with all objects in the sky revolving around it. That was the Aristotelian view, held as doctrine by Church authorities. With knowledge of a second center of heavenly motion, Galileo challenged the Church. Easy to guess what happened next: Lucy, you got some ‘splaining to do.

Ganymede was imaged and measured by the space probe Galileo in 1996. NASA Ames Research Center was associated with the project. The moon showed surprising surface ice tectonic patterns. Unusual for a moon, it was found to have an iron core and a magnetic field.

This moon was named for the son of the King of Troy, the most beautiful of all mortals in Greek mythology. He was carried off by the gods, ‘That he might fill the cup of Zeus.’ What’s up with that? In one of my fav’ childhood books, Farmer in the Sky (Robert Heinlein, 1950), Ganymede is the main scene location.
