The Cassini orbiter weighed 2,125 kg (4,685 pounds) and was 6.7 metres (22 feet) long and 4 metres (13 feet) wide. Because Jupiter and Saturn have nearly identical composition, Jupiter's higher density indicates that its interior is more compressed than Saturn's. b ring. sransomereynolds.

Using this, Cassini's controllers are able to guide the spacecraft on a tour of Saturn's moon system even though the spacecraft doesn't have much of its own power. When Cassini passes Titan inside its orbit of Saturn, Cassini's orbital semi-major axis is decreased. Using this, Cassini's controllers are able to guide the spacecraft on a tour of Saturn's moon system even though the spacecraft doesn't have much of its own power. The gravitational pull of Saturn's moon Mimas slowly pulled most of the material out from what is now the Cassini division due to its orbiting position.

The Cassini division is caused by the pull of one of Saturn's moons called Mimas. All probably look much like they did when the solar system first formed. 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 . Which moon has the most substantial atmosphere? "The Cassini Division" has a little bit of everything -- fast action, snappy dialogue, evocative descriptions, speculation on the nature of consciousness, and enough trippy political-economic speculation to entertain (or annoy) Vernor Vinge and Iain Banks fans.

Astronomy 101 Ch 10. All have cores of about the same mass, but differ in the amount of surrounding hydrogen and helium. A ring particle in the Cassini division would go around Saturn twice for every time Mimas goes around once; this is called a "2:1 resonance orbit". Use Newton’s Law of Gravity to calculate the acceleration of a Cassini Division particle due to the gravity of Mimas if M Acceleration = G ----- in meters/sec2 R2 where G = 6.67x10-11, M is the mass of Mimas in kilograms and R is the distance in meters. Learn cassini with free interactive flashcards. Accretion took longer further from the Sun, so the more distant planets formed their cores later and captured less gas from the solar nebula than the closer jovian planets. Cassini Division from Mimas is 67,000 kilometers. 87 terms. A large gap, visible from Earth, produced by an orbital resonance with the moon Mimas What is the most important reason why an icy moon is more likely to be geologically active than a rocky moon of the same size? It is about 4,800 kilometers wide, although this varies quite a bit around the planet. 41 terms. Why do Uranus and Neptune have blue methane clouds but Jupiter and Saturn do not? The gaps are produced by the gravitational pull of one or more of Saturn's many moons on the tiny particles in the rings. they exist inside the Roche limit of a planet, but do cannot clump togehter b/c of tidal forces.
