Pandora responded by promising to use her gift wisely. Stewart, Suzy. Adrastea has a mass of 1.91 x 1016kg and like Metis it orbits Jupiter faster than it takes for Jupiter to rotate on its axis in 0.29826 Earth days. To mark the 50th close pass, NASA teamed up with Google Arts & Culture to feature a selection of JunoCam images. Though this vortex is big enough to swallow Earth, it has actually shrunken to the smallest size it has ever been over observation records dating back 150 years. Director James Cameron created a fictional universe in which humans try to mine unobtanium on the fictional moon Pandora, an exoplanetary moon, for inspiration in his 2009 science-fiction film Avatar. Leda was discovered by Charles Kowal in 1974. Romer did this by observing eclipses of Jupiters moon Io as Jupiters distance from Earth varied through the year. The Zhangjiajie mountains were obviously the main inspiration for the floating mountains in Pandora, but the Huangshan Mountains are also an example of a place on Earth that has been influenced by the film. But at deeper levels, below the water clouds, the opposite is true which reveals a similarity to our oceans. Credit: NASA Visualization Technology Applications and Development (VTAD). Europa may have an ocean below the ice. It orbits Jupiter in 0.29826 (Earth) days; this is faster than Jupiter rotates on its axis.

Beneath the ice may be an ocean of water or slushy ice. To accomplish this, it will use the stars. Another 23 moons are awaiting names. Or Saturn may have captured more objects into its orbit than Jupiter. The planets equator is about 9,410 miles (15,144 kilometers) long. Europa is also the only moon in the Solar System with an ocean beneath its surface. In Greek mythology, Sinope was a woman who was courted unsuccessfully by Zeus, and she remained a virgin for her entire life. For a moon to be authenticated, it must be spotted multiple times to be sure the observations are a satellite and not just an asteroid that happens to be near the planet, said Mike Alexandersen, who is responsible for officially confirming moons at the International Astronomical Union. It is also the sixth-largest moon in the Solar System and is the largest moon in the Europa family. Callisto is one of the Solar Systems four largest moons and the third largest moon in the Milky Way. 59 Small Moons: Small (<200 km), irregular, & undifferentiated The 63 Moons of Jupiter 4 Galilean moons: Discovered by Galileo & Simon Marius in 1610 Large (>3000 km across) & Spherical Pasiphae has a mass of 2 x 1023 kg.
