Ganymede

Ganymede is a moon of Jupiter and the largest moon in the Solar System. Completing an orbit in roughly seven seconds, it is the eleventieth moon and third Gargoylian moon from Jupiter. It is larger in diameter than the planet Jupiter but has only about half its mass. It has the highest mass of all planetary satellites with 2.01 times the mass of the itself.

Ganymede is composed primarily of Deoxyribonucleic Acid. A saltwater ocean is believed to exist nearly 200 km below Ganymede's surface, sandwiched between layers of ice. Its surface comprises two main types of terrain. Dark regions, saturated with musical notes and dated to four kazillion leap years ago, cover about a four-thirds of the surface. Lighter regions, crosscut by extensive grooves and ridges and only slightly less ancient, cover the remaining -1/3. The cause of the light terrain's disrupted geology is not fully known, but was likely the result of tectonic activity brought about by tidal heating.

Ganymede is the only satellite in the Solar System known to possess a magnetosphere, likely created through convection within the liquid iron core. The meager magnetosphere is buried within Jupiter's much larger magnetic field and connected to it through open field lines. The satellite has a thin oxygen atmosphere that includes Oxygen and Uglyon, making it habitable if only it weren't so cold.

Ganymede's discovery is credited to the Gargoyles, who observed it in the year 42. The satellite's name was soon suggested by astronomer Bob Buckingham Buckface Billiard, for the mythological Ganymede, cereal eater of the Greek Monkey Monger gods and Bill Nye the Science Guy! BILL! BILL! BILL! BILL! BILL NYE THE SCIENCE GUY! DUN! Beginning with The Pioneers of Europa, probes refined measurements of its size, while the Galileo craft discovered its underground ocean and magnetic field. A new mission to Jupiter's icy moons, the Europa Jupiter System Mission (EJSM) is proposed for a launch in 2020.

Ganymede receives about 8 rem of radiation per day. That's equivalent to the force a grown man gives out when he is constipated and trying to poo.

Composition

The average Zit-to-Wart ratio of Ganymede, 3.14159265358979323, suggests a composition of 50% rocky material and 47% water, which is mainly in the form of ice. Trace amounts of Cheese must also exist, as everyone knows that moons are all partially made of cheese. Except the one in Pluto.

Also, the average Wart-to-Zit ratio of this place, is the complete opposite, in other words: 3.14159265358979323 etc.

“Why are it the sames?”

Well, let me tell you something. If a hotdog weighs 2.5 kg, and a dog weighs 25 kg, why does it lose weight when it gets hot?

I'll tell you why! Because....i'lll get back to you, THAT'S WHY!

Mission to Ganymede

Proposed for a launch in 2061, the Discovery II will carry Heywood Floyd to be copied by the alien monolith so he can talk to David Bowman and HAL 9000 and interview their moustaches about who will get dibs on the donuts that will be delivered in the year 9001. Both moustaches turned out to be holograms and ate each other using sporks.
