<p>Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. </p>It is a gas giant with a mean radius of about nine times that of Earth. It only has one-eighth the density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn is named after the Roman god of riches and agriculture; its astronomical symbol (ā™„) represents the god's sickle. Saturn's interior is most likely composed of a core of iron--nickel and stone (silicon and oxygen compounds). Its center is surrounded by an intermediate layer of liquid hydrogen, a deep layer of metallic hydrogen and helium, and finally a gaseous coating. Saturn has a hue because of ammonia crystals at its atmosphere. An electric current within the hydrogen layer is thought to contribute to the planetary magnetic field, which is weaker than the Earth's, but has a magnetic moment of Saturn 580 times that of Earth because of Saturn's larger dimensions.



Saturn's magnetic field strength is of Jupiter's. The outer atmosphere is usually bland and lacking in contrast, although features can appear. Wind speeds on Saturn can reach 1,800 km/h (1,100 mph; 500 m/s), greater compared to Jupiter, but not as large as those on Neptune. In January 2019, astronomers reported that a day around the planet Saturn has been decided to be 10h 33m 38s + 1m 52sāˆ’ 1m 19s, according to studies of the world's C Ring.The world'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. At least 82 moons are known to orbit Saturn, of which 53 are named. Titan, the second-largest in the Solar System, and Saturn's largest moon, is the only moon in the Solar System to have a substantial atmosphere, and is larger than the planet Mercury, although less massive.

The Moon is an astronomical body orbiting Earth as its only natural satellite. It is the fifth-largest satellite in the Solar System, and by far the largest among planetary satellites relative to the size of the planet that it orbits (its primary). The Moon is, after Jupiter's satellite Io, the second-densest satellite in the Solar System among those whose densities are known. The Moon is thought to have formed about 4.51 billion years ago, not long after Earth. The most widely accepted explanation is that the Moon formed from the debris left over after a giant impact between Earth and a hypothetical Mars-sized body called Theia. New research of Moon rocks, although not rejecting the Theia hypothesis, suggests that the Moon may be older than previously thought.The Moon is in synchronous rotation with Earth, and thus always shows the same side to Earth, the near side. Because of libration, slightly more than half (about 59%) of the total lunar surface can be viewed from Earth. The near side is marked by dark volcanic maria that fill the spaces between the bright ancient crustal highlands and the prominent impact craters. After the Sun, the Moon is the second-brightest celestial object regularly visible in Earth's sky. Its surface is actually dark, although compared to the night sky it appears very bright, with a reflectance just slightly higher than that of worn asphalt. Its gravitational influence produces the ocean tides, body tides, and the slight lengthening of the day. The Moon's average orbital distance is 384,402 km (238,856 mi), or 1.



28 light-seconds. This is about thirty times the diameter of Earth. The Moon's apparent size in the sky is almost the same as that of the Sun, since the star is about 400 times the lunar distance and diameter. Therefore, the Moon covers the Sun nearly precisely during a total solar eclipse. This matching of apparent visual size will not continue in the far future because the Moon's distance from Earth is gradually increasing. The Moon was first reached by a human-made object in September 1959, when the Soviet Union's Luna 2, an unmanned spacecraft, was intentionally crashed onto the lunar surface. This accomplishment was followed by the first successful soft landing on the Moon by Luna 9 in 1966. The United States' NASA Apollo program achieved the only manned lunar missions to date, beginning with the first manned orbital mission by Apollo 8 in 1968, and six manned landings between 1969 and 1972, with the first being Apollo 11 in July 1969. These missions returned lunar rocks which have been used to develop a geological understanding of the Moon's origin, internal structure, and the Moon's later history. Since the 1972 Apollo 17 mission, the Moon has been visited only by unmanned spacecraft. Both the Moon's natural prominence in the earthly sky and its regular cycle of phases as seen from Earth have provided cultural references and influences for human societies and cultures since time immemorial. Such cultural influences can be found in language, lunar calendar systems, art, and mythology.
