5 ημέρες πριν · is Saturn's largest moon and the only moon in the solar system known to have clouds, a dense atmosphere, and liquid lakes. The diameter of its solid body is 5,150 km (3,200 miles) making it the second-largest moon in the solar system. It was discovered telescopically in 1655 by the Dutch scientist Christiaan Huygen. Is Saturn light enough to float?

6 Δεκ 2019 · The temperature of Saturn’s upper atmosphere is on average about -175C (-285F), quite cold for a gas giant, while below the clouds it gets considerably hotter. The atmosphere is composed of ammonia, ammonia hydrosulfide, and water that influence the planet's colorful appearance of a brownish-yellow.
14 Νοε 2012 · Saturn is made up predominantly of hydrogen, which it captured in the early stages of its formation. Most of the remaining composition is helium. Other elements, such as methane and ammonia,...
4 ημέρες πριν · Saturn’s atmosphere is composed mostly of molecular hydrogen and helium. The exact relative abundance of the two molecules is not well known, since helium must be measured indirectly. Currently the best estimate is that the planet’s atmosphere is 18 to 25 percent helium by mass.
Like Jupiter, Saturn is made mostly of hydrogen and helium. Its volume is 755 times greater than that of Earth. Winds in the upper atmosphere reach 1,600 feet (500 meters) per second in the...
