Saturn vs Pluto - Comparison

<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 (♄) 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 52s− 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.

Pluto (minor planet designation: 134340 Pluto) is an icy dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It was the first and the largest Kuiper belt object to be discovered. Pluto was discovered by Clyde Tombaugh in 1930 and declared to be the ninth planet from the Sun. After 1992, its status as a planet was questioned following the discovery of several objects of similar size in the Kuiper belt. In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term "planet" formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet. It is the ninth-largest and tenth-most-massive known object directly orbiting the Sun. It is the largest known trans-Neptunian object by volume but is less massive than Eris. Like other Kuiper belt objects, Pluto is primarily made of ice and rock and is relatively small—one-sixth the mass of the Moon and one-third its volume. It has a moderately eccentric and inclined orbit during which it ranges from 30 to 49 astronomical units or AU (4.

4–7.4 billion km) from the Sun. This means that Pluto periodically comes closer to the Sun than Neptune, but a stable orbital resonance with Neptune prevents them from colliding. Light from the Sun takes 5.5 hours to reach Pluto at its average distance (39.5 AU). Pluto has five known moons: Charon (the largest, with a diameter just over half that of Pluto), Styx, Nix, Kerberos, and Hydra. Pluto and Charon are sometimes considered a binary system because the barycenter of their orbits does not lie within either body. The New Horizons spacecraft performed a flyby of Pluto on July 14, 2015, becoming the first ever, and to date only, spacecraft to do so. During its brief flyby, New Horizons made detailed measurements and observations of Pluto and its moons. In September 2016, astronomers announced that the reddish-brown cap of the north pole of Charon is composed of tholins, organic macromolecules that may be ingredients for the emergence of life, and produced from methane, nitrogen and other gases released from the atmosphere of Pluto and transferred 19,000 km (12,000 mi) to the orbiting moon.
