Jupiter, the biggest planet in the solar system, was discovered in 1610. It’s been said all of the other planets in our solar system are able to fit inside the planet of Jupiter. Jupiter is the fifth planet in our solar system coming after the planet Mars. It is a gas planet. This means there is no solid surface, much like the sun. Because the planet is made of gases, the planet is made up of a variety of colors. Jupiter is known for what scientist call “The Great Red Spot”. The Great Red Spot is a bunch of clouds that are continuously swirling. It is like a hurricane on Earth, but much larger than our storms. NASA states that The Great Red Spot is an anticyclone swirling around a center of high atmospheric pressure that makes it rotate in…show more content… The surface is a large ice field with cracks and craters. This moon is the third largest in the solar system with a size almost equivalent to the planet of Mercury. It is the second largest moon of Jupiter. Callisto seems to be a dead world because this moon hardly has any activity going on. Callisto is the only body that has not undergone any new impacts on the surface since the first impacts marked their place on the surface. With that being said, its safe to agree with NASA that Callisto has the oldest landscape in the solar…show more content… The largest craters have been found diminished by the flow of the icy crust over time. There are two giant concentric ring, impact basins are found on Callisto. The largest is Valhalla. It has a bright central region that is 600 kilometers in diameter, and its rings extend to 3000 kilometers in diameter. The second is Asgard. It measures about 1600 kilometers in diameter.
From recent observations made by the Galileo spacecraft, Callisto appeared to be composed of a crust. Beneath the crust is a salty ocean. Beneath the ocean, is an interior that is not entirely one nor does it vary. Galileo data suggests that the interior is composed of rock and ice as depth increases. Meteorites have punctured holes in Callisto's crust, causing water to spread over the surface and forming bright rays around the crater. Callisto has no known
