Enceladus is the sixth-largest moon of Saturn and the 18th-largest in the Solar System. It is about 500 kilometers (310 miles) in diameter, [5] about a tenth of that of Saturn's largest moon, Titan. It is mostly covered by fresh, clean ice, making it one of the most reflective bodies of the Solar System.
Titan orbits Saturn at 20 Saturn radii or 1,200,000 km above Saturn's apparent surface. From Titan's surface, Saturn subtends an arc of 5.09 degrees, and if it were visible through the moon's thick atmosphere, it would appear 11.4 times larger in the sky, in diameter, than the Moon from Earth, which subtends 0.48° of arc.
Astronomers believe the mysterious “magic islands” on Saturn’s moon Titan are honeycomb-like frozen clumps of organic material that fall like snow on the moon.
One recently discovered moon, Aegaeon, resides within the bright arc of G Ring and is trapped in the 7:6 mean-motion resonance with Mimas. [27] This means that it makes exactly seven revolutions around Saturn while Mimas makes exactly six. The moon is the largest among the population of bodies that are sources of dust in this ring. [51]
In it, Saturn hangs over windswept snow and brown cliffs and outcroppings. The crags frame a glowing Saturn, floating huge, rings nearly edge-on, like a giant’s belt-buckle.
Saturn’s moon Enceladus may have all the ingredients necessary to host life, according to a new study based on data from Nasa’s Cassini spacecraft mission.. The spacecraft ended its mission in ...
Most known large icy moons belong to giant planets, whose orbits lie beyond the Solar System's frost line; the remainder (such as Charon and Dysnomia) formed around dwarf planets such as Pluto and Eris, typically in large impacts not unlike the impact thought to have formed Earth's moon. In the case of icy gas giant satellites, an additional ...
Phosphates have been found on Saturn’s moon Enceladus, in a new breakthrough discovery that boosts hopes for finding alien life in our solar system. It is the first time phosphorus has been ...
