E) gravitational interaction with Mimas. The rings themselves are made of trillions of little particles. Gravitational tidal stresses from both Jupiter and Europa. The large division is known as the Cassini division, named from the French astronomer Giovanni Cassini, division and is easily seen through a medium sized telescope. Shadings within the rings are even easier to discern. montereyjay. The Ringed Planet In 1675, Italian-born astronomer Jean-Dominique Cassini discovered a "division" between what are now called the A and B rings. What is the Cassini division of Saturn's rings? Above the F ring is a gap caused by the orbit of a small satellite. The Trojan asteroids The Trojan asteroids are groups of asteroids that share Jupiter's orbit. Because of his numerous contributions to our knowledge about the planet Saturn, Cassini was chosen as the name of the spacecraft flying to Saturn. It was discovered in 1675 by Giovanni Cassini at the Paris Observatory using a refracting telescope that had a 2.5-inch objective lens with a 20-foot-long focal length and a 90x magnification . With a radius of 36,183.7 miles (58,232 kilometers), Saturn is 9 times wider than Earth. The Cassini division in Saturn's rings is a gap in the rings, swept clear of debris by the gravitational tug of ____, a … Saturn has an extensive system of rings. Bigger gaps in the rings (such as the Cassini division) are the result of gravitational resonances with the moons of Saturn. - Saturn's excess heat. Saturn's main ring is the B ring. They Huygens probe of the ESA made a successful landing on, The atmosphere of Titan is composed mostly of, The erupting geysers of nitrogen gas on Triton, are caused by a not yet determined internal energy source, The largest moon in the solar system, bigger but not as massive as Mercury, is, Water erupting and spreading over the surface, The next moon likely to be broken up into a ring is, The surface of Europe is most like the Earth's, The weak magnetic fields around Europa and Ganymede were found during flybys of, To explain its magnetic field, Europa must have an ocean of, Two of the Galilean moons of Jupiter are the size of Mercury, and the two others re about as big as our moon. The length of a day on Saturn: 10 hours, 33 minutes and 38 seconds. read more. Search. Why is the F ring much narrower than the main rings? 14)What is the Cassini division of Saturn's rings? Just outside the A ring is the narrow F ring, shepherded by tiny moons, Pandora and Prometheus. Cassini found that much of the material for Saturn's E-ring—a diffuse ring outside the bright, main rings—comes from the moon Enceladus, which is venting icy particles and gas into space as it orbits Saturn. What did the Huygens probe photograph as it landed on Titan? One theory is that particles in these zones were gravitationally attracted by the moons of Saturn, and pulled into a new orbit. The Huygens Gap is the widest black swath near the middle of the image. Cassini division synonyms, Cassini division pronunciation, Cassini division translation, English dictionary definition of Cassini division. Log in Sign up. The Cassini's Division is where there is a gap in the rings that seperate ring A and B. What was the first gap discovered in the rings called, and who discovered it? The Cassini Division, named in honor of G. D. Cassini separates the brightest two. Which of the following rings of Saturn lies closest to the planet? Between the A and B Rings is a wide gap named the Cassini Division after Gian Domenico Cassini, who first glimpsed it through a telescope in 1675 and whose name planetary scientists have also given to the Cassini spacecraft exploring the Saturn system. A)a dark ring, visible from Earth, composed of dark, dusty particles B)the most opaque ring of Saturn, made of highly reflective ice particles C)the widest ring of Saturn, located between two large ring gaps D)the imaginary circle marking the halfway point of Saturn's rings He also discovered four of Saturn's moons. The surface of Europa, one of Jupiter's Galilean satellites, is characterized by a fractured crust of ice with evidence of ice rafts and areas of flooding at some earlier time. Earth makes passes through the ring plane every 13 to 15 years, about every half Saturn year, and there are about equal chances of either a single or three crossings occurring in each such occasion. You mean like the black bands going around the planet in this picture? Of the Jovian satellites, which shows the oldest, most cratered surface? nearer to their planet than any of the planet's large moons. Oh no! It is more inclined to the ecliptic than any of the eight planets. Details of Saturn's icy rings are visible in this sweeping view from Cassini of the planet's glorious ring system. It is named that because Atronimer Gean Domenico Cassini (French) Found it. The Cassini Division is a region 4,800 km (3,000 mi) in width between Saturn's A ring and B Ring. Titan, the shadow caster, is not shown. Giovanni Domenico Cassini discovered the division between Saturn's rings in 1675. The Cassini-Huygens mission was initially planned for a … Cassini division; Kepler gap; Colombo gap; 9. 3.
