Saturn






Named after the god of time, Saturn is the second largest planet in the solar system, yet it has the smallest density; strange as it seems , Saturn would actully float if immersed in an ocean, as it is less dense than water. Saturn's rings make the planet one of the most beautiful objects in the solar system.The tempreture is -180 degrese celcius.It takes 10 hours to spin and 30 years to orbit the sun.





Saturns Rings
One of the greatest fascinations of the solar system is the rings of Saturn.They are ussally visible with an amateur telescope,provided the planet is at the correct angle.The rings are located in the plane of Saturns equatour,and like the equatour they are inclined at 27 degreese to the orbital plane,which means that for a short period, the rings are facing an Earth-based observer edge-on when they are too thin to be seen from Earth.The first person to see the rings of Saturn Galileo when he was the first observer to look at the planet through a telescope in 1610.He had no idea what he was looking at.Galileo named the rings the 'ears' of Saturn,explaining that they might be huge mountain ranges extending high above the planet on both sides,or they might be twoother small planets.
