Who Discovered It

Few facts about Saturn need to be clarified as much as its discovery. The Romans, Greeks and Hindus all knew of its existence. Galileo did not discover Saturn in the 17th century, but he was the first to study its rings. Facts and Figures Saturn has an equatorial diameter of 107,500 km and a polar diameter of 119,600 km. its perihelion is 1,349,000 km; the aphelion is 1,508,900 km and the mean is 1,500,000 km. The rotation is 10.66 hours. Saturn has a revolution of 29.45 years. It has more than 60 satellites, all of which have orbits. Surface and Geology One of the established facts about Saturn is that it’s flat at the poles while projecting at the equator. This makes it more oblate than other planets. Another notable trait is that its density is less than water. However it has a dense core brought about by the gaseous atmosphere. Saturn is 20% smaller than Jupiter but its mass is only 95 times that of Earth. By contrast, Jupiter has a mass 300 times that of Earth. Its internal structure...

Also known as the Red River, the Colorado River is found in the northwest region of Mexico and southwest region of the United States. The natural course of the river starts at Grand Lake in Colorado and ends into the Gulf of California. The river is the source of water of the irrigation at Imperial Valley. In droughts, the flow of water is approximately 4,000 cubic feet per square. On the other hand, during severe floods, the water flow in the river is estimated to be 990,000 cubic feet per square. To learn more about the place, it is best to start with the history of the Colorado River. Historical Background Who discovered the Colorado River?
