Others have suggested that the mountains arose when the moon was first forming and spinning much faster, and thus shoving material toward the equator. Sheppard is perhaps most intrigued by its strange inclination. Most of Saturn’s regular moons, the ones that formed along with it, orbit along...
How many moons does Saturn has? How big is a red dwarf star? Who built the Saturn rocket? How big is Ceres compared to Pluto? How big is the planet Ceres? How big is the Sombrero Galaxy? How big is a blue giant star? How thick are Saturn's rings from top to bottom? Which plane...

How much does it weigh? How far is it from earth? Sun: The source of the light on earth is the sun. Sun is one of the stars made up of hydrogen and helium molecules. The nuclear fusion reaction between hydrogen and helium releases an enormous amount of energy. Answer a...

Starting with Earth, of course, we all know it has only one moon. It is also the only moon where humans have set foot. Our neighbor—Mars—where Elon Musk is likely totake usin the future (hopefully!) has two moons:PhobosandDeimos. They are dark and lumpy and much smaller than our ...
