Planets are composed of a very large cloud of dust and gas contracted into a disk. At the center, a ball of gas formed into a star—our Sun. Many small balls of gas and dust orbiting our new Sun contracted into planets. ---- Answer provided by ... /For%20Kids/KidstoSpace.html Click here Category:Kids To Space Category:Kids To Space - PLANETS

... and south poles. We strongly suspect that water is present on many of the other planets in our solar system, but have not physically confirmed its existence. Because oxygen and hydrogen ... atmospheres that are dense enough to hold hydrogen, oxygen, and other gases around the planet. On those planets, unless water or water-ice is in cold-traps or regions hidden from their sun's energy (usually in deep craters at the planet's poles) it will very likely simply sublimate away into space. ---- Answer provided by Joe ...
