Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It has a hot interior, reaching 11,700°C at its core, and radiates 2,700 times more energy into space than Jupiter. At least 82 moons are known to orbit Saturn, of which 53 are officially named.
About Saturn in brief
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine times that of Earth. Saturn is named after the Roman god of wealth and agriculture; its astronomical symbol represents the god’s sickle. At least 82 moons are known to orbit Saturn, of which 53 are officially named. Saturn’s rotation causes it to have the shape of an oblate spheroid; that is, it is flattened at the poles and bulges at its equator. The planet’s most famous feature is its prominent ring system, which is composed mostly of ice particles, with a smaller amount of rocky debris and dust. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. Wind speeds on Saturn can reach 1,800 kmh, higher than on Jupiter, but not as high as those on Neptune. It has a hot interior, reaching 11,700°C at its core, and radiates 2,700 times more energy into space than Jupiter. The outermost layer spans 1,000km and consists of gas and liquid hydrogen, followed by a thicker liquid hydrogen layer, and a gaseous outer layer. The interior of Saturn is similar to that of Jupiter, having a small rocky core surrounded by hydrogen and helium, with traces of various trace amounts of variousatiles in the deeper layers. It only has one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive than Earth.
Together, Jupiter and Saturn hold 92% of the total planetary mass in the solar System. Despite consisting mostly of hydrogen and. helium, most of Saturn’s mass is not in the gas phase, because hydrogen becomes a non-ideal liquid when the density is above 0. 01 gcm3. The temperature, pressure, and density inside Saturn all rise steadily toward the core, which causes hydrogen to be a metal in the depths of the planet. In January 2019, astronomers reported that a day on the planet Saturn has been determined to be 10h 33m 38s + 1m 52s− 1m 19s , based on studies of thePlanet’s C Ring. The equatorial escape velocity of nearly 36 kms is much higher than that for Earth. Titan, Saturn’s largest moon, is larger than the planet Mercury, although less massive, and is the only moon in theSolar System to have a substantial atmosphere. Saturn’s core is considerably denser than water, but the average specific density of the planets is 0. 69 g cm3 due to the atmosphere. Although Jupiter has 318 times Earth’s mass, and Saturn is 95 times Earth’s mass. Jupiter is more dense than Saturn, but Saturn’S core must be 9–22 times the mass of Earth, which corresponds to a diameter of about 25,000,000 km.
