It is the smallest Galilean moon. It's mass is 4.8e+22 kilograms.]]> 2018-03-25 21:18:49 UTC https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884688 Distance: erik1350 https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884769 On average (at any orbital point), Europa's distance from the sun is about 780 million kilometers, or 450 million miles away.

Europa's orbital distance from Jupiter is around 415,000 miles.]]> 2018-03-25 21:19:28 UTC https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884769 Atmospheric Composition: erik1350 https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884842 Europa's surface temperature at the Equator will be under (-160) degrees Celsius, and at the poles of the moon, the temperature will be a blistering (-220) degrees.]]> 2018-03-25 21:19:57 UTC https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884842 Gravity: erik1350 https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884853 Europa's gravity is only 13 percent of Earth's gravity, resulting in a very thin atmosphere. This also means that Europa does not feature any weather or wind.]]> 2018-03-25 21:20:02 UTC https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884853 Period of Revolution: erik1350 https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884928 It takes about 80 hours (3 1/2 Earth days) for Europa to orbit Jupiter. It takes the same amount of time for it to complete one revolution. This means that one day on Europa is one year. 
Europa orbits in an elliptical pattern,  and the pull from Jupiter only affects the closer half of the moon, therefore causing the surface of Europa to stretch and relax.]]> 2018-03-25 21:20:39 UTC https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884928 Bibliography: erik1350 https://padlet.com/erik1350/iq4oep5sc5g8/wish/245884950 Howell, E.

Scientists predict that there is a subterranean ocean under this ice sheet, which could harvest life. The surface ice sheet, which is 15 miles thick, makes Europa one of the most reflective moons in our solar system. The face of the moon also lacks the rough, cratered appearance of sister moons such as Callisto and Ganymede. According to NASA, jets of water which have been observed at the surface, may be caused by hydro-thermal vents near the ocean floor. This would conclude that the moon is geologically active, like Earth.]]> 2018-03-25 22:27:43 UTC https://padlet.com/erik1350/iq4oep5sc5g8/wish/245891927 Age: erik1350 https://padlet.com/erik1350/iq4oep5sc5g8/wish/245892339 Europa is estimated to be the same age as Jupiter, and other neighboring moons such as Ganymede, at 4.5 billion years old.]]> 2018-03-25 22:31:15 UTC https://padlet.com/erik1350/iq4oep5sc5g8/wish/245892339 NASA Missions: erik1350 https://padlet.com/erik1350/iq4oep5sc5g8/wish/245893067 NASA's Galileo mission is responsible for what we know about Europa the most. Launched in 1989, the Galileo mission took 6 years to reach Jupiter and it remained in orbit from from 1995 until 2003.
