Aside from the marked thermal difference between Uranus and Neptune, these two planets differ from the other Jovian planets in several other (related) ways: (1) relative abundance of hydrogen and helium, (2) abundance of heavy elements, (3) density profiles, (4) internal structure, (5) degree of homogeneity, and (6) temperature profiles.15 It . Answer: Jupiter and Saturn consist mainly of hydrogen and helium; most of the mass of Jupiter consists of an ultra-high-pressure form of hydrogen called metallic hydrogen, whereas most of Saturn is molecular hydrogen. Found inside – Page 88In 1989 Voyager 2 found that , like the other three Jovian planets , Neptune has winds and storms . Neptune's winds are the fastest in our Solar System at 2000 kilometres per hour . The winds don't travel in the same direction as the ... Jupiter and Saturn have similar interiors, with layers extending outward of metallic hydrogen, liquid hydrogen, gaseous hydrogen, and topped with a layer of visible clouds. . PLAY. The rings are located closer to the planets than any of their moderately sized or large moons, but the inner edge of the rings is still well above the planet's cloud tops. Spell. (or . Neptune's Great Dark Spot was nearly 10,000 kilometers long (Figure 7). Outer Planets DRAFT. Uranus also has rings, and the images that reveal its rings emphasize how tilted this planet is compared to Saturn. Uranus (left) and Neptune (right). Found inside – Page 343Magnetic Field Like the other Jovian planets, Neptune has a powerful magnetic field and a large magnetosphere. Voyager found that Neptune's magnetic field was 25 times stronger than Earth's, though the planet is so large that the field ... Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA. Why are the jovian planets so different from the terrestrial planets?

An increase in temperature and density means an increase in pressure. The reason for this is that the planets have elliptical orbits and none of them are perfect circles. Thus, if a small object orbiting the Sun happens to pass too close to Jupiter, it can become captured into an orbit around Jupiter. The chemical composition of Titan's atmosphere and its temperature and pressure have led astronomers to propose that there may be bodies of liquid methane and/or ethane the size of lakes on the surface and it may rain liquids that are similar to gasoline. It's well known that the four Jovian planets - Jupiter, Saturn, Uranus and Neptune - are much bigger than the four terrestrial planets - Mercury, Venus, Earth and Mars. CVA Astronomy Module 5 A5.02.3 Jovian Planets Comparative Planetology Student Name: London Examples of Terrestrial Planets are Mercury, Venus, Earth, and Mars. Jovian planets include Jupiter, Saturn, Uranus, and Neptune. In contrast, many moons and rings orbit each of the jovian planets. NASA's real-time science encyclopedia of deep space exploration. How do you think the Sun's appearance would differ if it had no convection inside? About 50 years after Uranus was discovered. The less mass makes the outer lying layers' weight less on Saturn. The College of Earth and Mineral Sciences is committed to making its websites accessible to all users, and welcomes comments or suggestions on access improvements. The rings look flat because the particles all orbit in essentially the same plane. Compared to the other planets in our solar system, Jupiter, Saturn, and Neptune have.? . Their main difference is their composition. Below is an image of Triton, a strange moon orbiting Neptune. Jovian Planets •The Jovian planets: Jupiter, Saturn, Uranus and Neptune •Their masses are large compared with terrestrial planets, from 15 to 320 times the Earth's mass •They are gaseous •Low density •All of them have rings •All have many satellites •All that we see of these planets are the top of the clouds Additional reading from www.astronomynotes.com. Pluto doesn't fit well into either planetary category. View A5.02.3 Jovian Planets Comparative Planetology.docx from ASTRONOMY 105 at Georgia Virtual School.

The frost line marked an important dividing point in the solar nebula. when viewed against the solar disk) is a large, bright feature often in a loop shape extending outward from the Sun's surface.
