Jupiter Io Research Paper

There are 67 moons that orbit Jupiter but the four largest are Io, Europa, Ganymede and Callisto. The man who found the moons, was Galileo Galilei who was born in Pisa in 1564, in 1581 he went to the University of Pisa to study medicine. But was sidetracked by mathematics, in 1609 is when he built his first telescope but it wasn’t no ordinary telescope. This telescope Galileo built he could discover uncharted territory. To Galileo it seemed plainly obvious that the universe was not the perfect symmetrical and earth centered universe that most people believed it was. Instead he found a messy off center and chaotic universe one that was infinitely fascinating. So with his unique telescope discovered the moons of Jupiter, the rings of Saturn, the phases of Venus, sunspots and the rugged lunar surface. Upon discovering that Jupiter has moons in 1610, he named them after the power mediji family to incur their patriotism protection. On October 18, 1989, two space craft’s took off to Jupiter for Galileo’s mission. To study the design of the planets, atmosphere, satellites and surrounding magnetosphere. IO is the innermost, which is named after a priestess of Hera who became Zeus’ lover. With a diameter of 3,642 …show more content…
While it is larger than the planet Mercury, the fact that it is an icy world means that it has only half of Mercury’s mass. It is also the only satellite in the Solar System known to possess a magnetosphere, likely created through convection within the liquid iron core. Ganymede is composed primarily of silicate rock and water ice, and a salt-water ocean is believed to exist nearly 200 km below Ganymede’s surface – though Europa remains the most likely candidate for this. Ganymede has a high number of craters, most of which are now covered in ice, and boasts a thin oxygen atmosphere that includes O, O2, and possibly O3 (ozone), and some atomic
