 Europa is the sixth moon of Jupiter’s 67 moons.  It is frozen over by ice.  There is a possibly of water underneath its surface.

 Supposedly, Europa has an outer layer of water around 100 km (62 mi) thick  The crust is estimated to have undergone a shift of 80°  Europa's surface temperature averages about 110 K

 Its radius is 1,569 km  Its density is 3.01 g/cm  An axial tilt of 0.1°  A volume of 1.593×10 10  Has a Mass of 4.80×10 22

 Scientists belive that Europa has an outter layer of water that is 100km thick  Probably sea of salty liquid  This layer is predicted to be made of both water and ice  It is the sixth largest moon and the fifteenth largest object in the universe  It also holds a metalic iron core  Parts of Europa’s crust is said to have shifted by about 80 degrees which would not be possible without the pressence of water

 One of the smoothest objects in the solar system  The surface of Europa is smooth because it is very young and active  The radiation is very high which would cause harm to human beings who endure it  The icy crust on Europa cause it to be shiny and reflective  The surface is around twenty to 180 million years old

 The dark crisscrossing lines on the surface of Europa are its most remarkable feature  The larger lines on the surface are about 20 miles across!  The reason for the cracks are said to be because the crust opens up to expose the expanding warmer layers beneath  Jupiter’s pull and the fact that Europa’s crust rotates faster than its core could explain the cracks also

 There are also features called lenticulae, they are dark and raised circular landforms  The domes that are formed seem to be pushed up from under the crust  Reasoning behind this is that the warmer ice pushes up through the colder ice against the surface

 Europa’s atmosphere is said to be made up of mostly oxygen molecules  The surface pressure of Europa is 10^-12 times of Earths  But it is not that type of oxygen found on earth, the oxygen on Europa is starts with water then is split by radiation forming hydrogen and oxygen molecules  The oxygen stays in the atmosphere while the hydrogen molecules are too light and escapes the atmosphere
