About 764 Earths could fit inside Saturn. [58] Whereas temperatures on Saturn are normally −185 °C, temperatures on the vortex often reach as high as −122 °C, suspected to be the warmest spot on Saturn. 5 (1 Ratings ) Solved. This was first noted in Voyager I spacecraft images and then later observed more closely by the Cassini spacecraft. This abundance variance may be explained by meteor bombardment. Although it is made of gases, Saturn may have a small rocky core. [71] This vortex is comparable to the size of Earth, and it has winds of 550 km/h. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than the Earth's, but has a magnetic moment 580 times that of Earth due to Saturn's larger size. How big (compared to our moon) would Saturn look from Titan's surface? From the angle at which he observed it, Galileo surmised that Saturn wasn't a single star, but was actually three: a large middle star with two earlike appendages sticking out of it, which he thought might be large moons.Galileo observed Saturn for more than a year. Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally a gaseous outer layer. These jets of icy particles are emitted into orbit around Saturn from vents in the moon's south polar region. [151], Starting in early 2005, scientists used Cassini to track lightning on Saturn. [161] On 15 September 2017, the Cassini-Huygens spacecraft performed the "Grand Finale" of its mission: a number of passes through gaps between Saturn and Saturn's inner rings. [55], The winds on Saturn are the second fastest among the Solar System's planets, after Neptune's. Rings Size Saturn is 36,164mi . It lacks a definite surface, though it may have a solid core. [162][163] The atmospheric entry of Cassini ended the mission. Question : How big Saturn? Orbital resonance mechanisms, including secular resonance, are believed to be the cause of the missing Saturnian trojans. Polygonal shapes have been replicated in the laboratory through differential rotation of fluids. [18] It takes approximately 29.5 years for the planet to complete an entire circuit of the ecliptic against the background constellations of the zodiac. [18] Most of the magnitude variation is due to the inclination of the ring system relative to the Sun and Earth. [22][23][24] Saturn is named after the Roman god of wealth and agriculture; its astronomical symbol (♄) represents the god's sickle. [26] The outer atmosphere is generally bland and lacking in contrast, although long-lived features can appear. How big Saturn? By comparison, Jupiter is about 1.2 times as big as Saturn and 3.2 times as massive. [130], The Greek scientist Ptolemy based his calculations of Saturn's orbit on observations he made while it was in opposition. Its intelligence or beneficial spirit is 'Agȋȇl (Hebrew: אגיאל‎‎, romanized: ʿAgyal),[136] and its darker spirit (demon) is Zȃzȇl (Hebrew: זאזל‎, romanized: Zazl). This variance may be caused by geyser activity on Saturn's moon Enceladus. [104], Saturn's moon Enceladus, which seems similar in chemical makeup to comets,[105] has often been regarded as a potential habitat for microbial life. [64] The pattern's origin is a matter of much speculation. It proved that Titan's atmosphere is impenetrable in visible wavelengths; therefore no surface details were seen. I believe they are tidally locked. If you could find a bathtub big enough, Saturn would float in it. The equatorial diameter of Saturn is 120,536 km ± 8 km (74,898 ± 5 mi) – or the equivalent of almost 9.5 Earths. [152], In 2006, NASA reported that Cassini had found evidence of liquid water reservoirs no more than tens of meters below the surface that erupt in geysers on Saturn's moon Enceladus. Only Jupiter is larger. Accounting 1 Year Ago 3 Views. Previous Question. [48][49][50] The upper clouds are composed of ammonia crystals, while the lower level clouds appear to consist of either ammonium hydrosulfide (NH4SH) or water. It sent back the first high-resolution images of the planet, its rings and satellites. During the early 20th century, research on Titan led to the confirmation in 1944 that it had a thick atmosphere – a feature unique among the Solar System's moons. [30] 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 second phase began in the 17th century, with telescopic observations from Earth, which improved over time. The total mass of these heavier elements is estimated to be 19–31 times the mass of the Earth, with a significant fraction located in Saturn's core region. Titan, the largest moon, comprises more than 90% of the mass in orbit around Saturn, including the rings. This atmospheric condition has a six-sided jet stream that creates a hexagon-shaped pattern. [40][141] When Earth passes through the ring plane, which occurs twice every Saturnian year (roughly every 15 Earth years), the rings briefly disappear from view because they are so thin. [47], Trace amounts of ammonia, acetylene, ethane, propane, phosphine, and methane have been detected in Saturn's atmosphere. With an average orbital speed of 9.68 km/s,[10] it takes Saturn 10,759 Earth days (or about ​29 1⁄2 years)[78] to finish one revolution around the Sun. Unfortunately, during the flyby, the probe's turnable camera platform stuck for a couple of days and some planned imaging was lost. [157] In July 2006, images were returned of hydrocarbon lakes near Titan's north pole, the presence of which were confirmed in January 2007. As with all the planets in the Solar System, occultations of Saturn occur in "seasons". The examination of Saturn's gravitational moment, in combination with physical models of the interior, has allowed constraints to be placed on the mass of Saturn's core. [126] In ancient Greek, the planet was known as Φαίνων Phainon,[127] and in Roman times it was known as the "star of Saturn". Its oblate shape is apparent even in a … Saturn is about 75 thousand miles (120,000 km) in diameter and is almost ten times the diameter of Earth. [160] In April 2013 Cassini sent back images of a hurricane at the planet's north pole 20 times larger than those found on Earth, with winds faster than 530 km/h (330 mph). In addition, Pioneer 11 measured the temperature of Titan. The average distance between Saturn and the Sun is over 1.4 billion kilometers (9 AU). [110][111][112] A 2015 flyby by Cassini through a plume on Enceladus found most of the ingredients to sustain life forms that live by methanogenesis. [167], From time to time, Saturn is occulted by the Moon (that is, the Moon covers up Saturn in the sky). [34], 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 g/cm3, which is reached at a radius containing 99.9% of Saturn's mass. An alternative or additional mechanism may be generation of heat through the "raining out" of droplets of helium deep in Saturn's interior. [62] The entire structure rotates with a period of 10h 39m 24s (the same period as that of the planet's radio emissions) which is assumed to be equal to the period of rotation of Saturn's interior. Let’s take a look at Saturn compared to Earth.

By this measure, Saturn’s equatorial diameter is 120,536 km (74,898 miles). Jupiter, Uranus, and Neptune, the other giant planets in the Solar System, are also oblate but to a lesser extent. Saturn also appears brighter when the rings are angled such that they are more visible. Based on radio emissions from the planet detected by Voyager 1 and Voyager 2,[81] System III has a rotation period of 10h 39m 22.4s (810.8°/d). [26] As a result, Saturn's magnetosphere is much smaller than Jupiter's. Saturn also measures in at 108,728 km from pole to pole. First, let’s just look at Saturn’s physical characteristics. Live, Love, Learn (Uranus, and occasionally 4 Vesta, are visible to the naked eye in dark skies.) The observation and exploration of Saturn can be divided into three phases. The outermost layer spans 1,000 km and consists of gas. How big is the planet? If the periodicity is maintained, another storm will occur in about 2020. [27] 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 the planet's C Ring. [10] Jupiter, Uranus, and Neptune, the other giant planets in the Solar System, are also oblate but to a lesser extent. There are two main hypotheses regarding the origin of the rings. [29], Saturn is a gas giant because it is predominantly composed of hydrogen and helium. 7,251 + French lore. The combination of the bulge and rotation rate mea… [103] On 23 June 2014, NASA claimed to have strong evidence that nitrogen in the atmosphere of Titan came from materials in the Oort cloud, associated with comets, and not from the materials that formed Saturn in earlier times. Saturn's magnetic field strength is around one-twentieth of Jupiter's. [85], In March 2007, it was found that the variation of radio emissions from the planet did not match Saturn's rotation rate. Saturn has the lowest mean density of any of the planets. View Solution. [149], In November 1980, the Voyager 1 probe visited the Saturn system. Saturn's finer cloud patterns were not observed until the flybys of the Voyager spacecraft during the 1980s. [20][21] It only has one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. [26] Saturn's magnetosphere, like Earth's, produces aurorae.[77]. In the 21st century, telescopic observations continue from Earth (including Earth-orbiting observatories like the Hubble Space Telescope) and, until its 2017 retirement, from the Cassini orbiter around Saturn. How big is Saturn? [68][69] Eyewall clouds had not previously been seen on any planet other than Earth. [38] This is surrounded by a thicker liquid metallic hydrogen layer, followed by a liquid layer of helium-saturated molecular hydrogen that gradually transitions to a gas with increasing altitude. However, the giant planet spins … They are composed predominantly of water ice, with trace amounts of tholin impurities and a peppered coating of approximately 7% amorphous carbon. [93] Saturn's second-largest moon, Rhea, may have a tenuous ring system of its own,[94] along with a tenuous atmosphere. Water ice clouds begin at a level where the pressure is about 2.5 bar and extend down to 9.5 bar, where temperatures range from 185–270 K. Intermixed in this layer is a band of ammonium hydrosulfide ice, lying in the pressure range 3–6 bar with temperatures of 190–235 K. Finally, the lower layers, where pressures are between 10–20 bar and temperatures are 270–330 K, contains a region of water droplets with ammonia in aqueous solution. Saturn ,the sixth planet from the Sun and the second largest planet in our solar system. The spacecraft also studied Saturn's rings, revealing the thin F-ring and the fact that dark gaps in the rings are bright when viewed at high phase angle (towards the Sun), meaning that they contain fine light-scattering material. Saturn is about ten times bigger across than Earth. If Earth were the size of a nickel, Saturn would be about as big as a volleyball. While approaching Saturn in 2004, Cassini found that the radio rotation period of Saturn had increased appreciably, to approximately 10h 45m 45s ± 36s. The equatorial diameter of Saturn is 120,536 km ± 8 km (74,898 ± 5 mi) – or the equivalent of almost 9.5 Earths. Cool Cosmos is an IPAC website. Saturn is about ten times farther from Earth than the sun.
