Jupiter's sixth moon
- The Distance from the Sun:
Europa is 485 million miles or 780 kilometers away from the Sun. Europa is the sixth closest moon to Jupiter.
- Size of Planet/Mass:
Europa is 3121.6 km in diameter and the mass is 47,998,438,387,492.7 billion kg.
- Force of Gravity compared to Earth:
The gravity on Europa is 1.315 m/s² compared to Earth.
- Distance from Earth:
Europa's distance from Earth is 390.4 million miles or 627 kilometers.
- Length of a yeAr:
One day on Europa lasts as long as one year - 3.5 Earth days. That means a day on Europa takes the same length of time as one year on Europa.
- Time for one rotation:
It takes 3.5 Earth days to rotate around Jupiter.
- Temperature on Planet:
The mean surface temperature of Europa is -171.15 C ° (-274.07 F °).
- Gases that Make up the Atmosphere:
Europa has a weak oxygen atmosphere which is the Sun hitting water molecules on it's surface. They break those molecules into hydrogen and oxygen atoms leaving a tenuous oxygen based atmosphere.
- What type of weather:
The surface of Europa is made of frozen water and has the smoothest surface and lacks mountains and craters.There are very few craters on the surface of the moon because it is tectonically active.
The moon is one of the brightest objects in the solar system with an albedo (light reflectivity). Radiation levels on the sufrace could also cause severe illness and death in a human in one day. There is also a liquid ocean somewhere between 100 km (60 miles) beneath Europa's thick, icy, crust.
- Planet's Terrain:
Thick, icy crust on Europa. a liquid saltwater ocean, and is the smoothest object in the solar system. Europa's surface is made of frozen water but lacks mountains and craters and scientists believe there is a rocky seafloor.
