Oct 2010 Io in True Color Credit: Galileo Project, JPL, NASA The strangest moon in the Solar System is bright yellow. Io's colors derive from sulfur and molten silicate rock. The unusual surface of Io is kept very young by its system of active volcanoes.
Callisto, Jupiter’s second largest moon, is roughly the same size as the planet Mercury but only about a third of the mass. It is the outermost of Jupiter’s four large Galilean satellites and orbits at an isolated km from the planet.
How much water on earth? In this illustration, the blue ball represents the volume of all the water on earth, relative to the size of the earth. The tiny speck to the right of the blue ball represents Earth’s fresh water.
Io, one of Jupiter's many moons and larger than our own. With over 400 active volcanoes, Io is the most geologically active object in the Solar System. Seems interesting how all of the biggest moons are related to people that Jupiter had affairs with.
If the icy surface of Pluto's giant moon Charon is cracked, analysis of the fractures could reveal if its interior was warm, perhaps warm enough to have maintained a subterranean ocean of liquid water, according to a new NASA-funded study.
facts : The Solar System consists of the and the astronomical objects gravitationally bound in orbit around it, all of which formed from the collapse of a giant molecular cloud approximately billion years ago. of the system’s mass is in the Sun.
