s solar system. " Its mass represents more than two-thirds of the total mass of all the planets, or 318 times the mass of the Earth. Jupiters density is quite low at 1.3-g/cubic cm. The atmosphere of Jupiter contains water, ammonia, methane and carbon. It is thought by scientists that there are three cloud layers. The wind activity on Jupiter is quite fierce and moves in jet streams parallel to the equator. The weather on Jupiter is still very hard for scientists to understand. There is not enough information to truly understand how the weather is on this planet. Jupiter is most known by the normal citizen by the rings it has. These " rings are very diffuse. The ring particles must generally be about as big as the wavelength of light, that is, only a few microns " (Sipiera 154). That is why these rings are faint or diffuse. The rings are what Jupiter is known for. Saturn is a planet which is also known for its rings and when viewed has a yellow or grayish color. The color is from the gaseous atmosphere and the dust particles in that atmosphere. The atmosphere is mostly a clear hydrogen-helium atmosphere. There are also traces of methane, phosphine, ethane, and acetylene. This atmosphere is much different than that of the Earth's. Saturn orbits the sun with a period of 29.4577 tropical years. It is 1.427 billion Km away from the sun and is therefore a cold planet. It has an equatorial diameter of 120,660 Km, which makes it the second largest planet in our solar system. The next planet is Uranus. The main problem scientists have with Uranus is that, "the lack of visible surface features means that it is difficult to measure the rotation period of Uranus "(Hunt, Moore 388). Uranus has an equatorial diameter of 51,000 Km, which is almost four times as much as Earth. The atmosphere is mostly methane gas and therefore the planet has a red tint or a bluish green color. Uranus also has rings but unlike Saturn these rings have almost no small pa...
