The Giant Planets. The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and helium, with 75% of their mass being hydrogen and 25% helium. On Earth, both hydrogen and helium are gases, so Jupiter and Saturn are sometimes called gas planets.A gas giant is a giant planet composed mainly of hydrogen and helium. Gas giants are also called failed stars because they contain the same basic elements as a star. Jupiter and Saturn are the gas giants of the Solar …A human being would not survive on Saturn as it has no surface. The only way a human could survive a trip to Saturn would be in a spacecraft doing a flyby. Saturn is known for its spectacular rings, which are the most prominent in our solar...The Composition of Planetary Atmospheres 4.1 All of the planets in our solar system, and some of its smaller bodies too, have an outer layer of gas we call ... Saturn, Uranus and Neptune. The objects with the least percentage are Venus, Earth, Moon, Mars, Titan, Pluto. With the exception of Mercury, which has a very thin atmosphere, the high-Each planet type varies in interior and exterior appearance depending on composition. Gas giants are planets the size of Saturn or Jupiter, the largest planet in our solar system, or much, much larger. …Saturn’s Atmosphere: The outer atmosphere of Saturn contains 96.3% molecular hydrogen and 3.25% helium by volume. The gas giant is also known to contain heavier elements, though the proportions ...What is Neptune Made Of? Neptune, like Uranus, is one of the two outer planets known as an "ice giant." Made up of more ices than Jupiter and Saturn, the chilly body almost seems to be in a class ...Asteroids, sometimes called minor planets, are rocky remnants left over from the early formation of our solar system about 4.6 billion years ago.

Asteroids range in size from […]Overview Saturn is the sixth planet from the Sun and the second largest planet in our solar system. Adorned with a dazzling system of icy rings, Saturn is unique among the planets. It is not the only planet to have rings, but none are as spectacular or as complex as Saturn’s. Like fellow gas giant Jupiter, Saturn […] Over time, this in-fall adds mass to a planet and alters its chemical composition. Saturn is a massive gas giant planet with a radius of some 60,000km, about 9.5 times that of Earth, and a mass of ...The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and ...Dark, cold, and whipped by supersonic winds, ice giant Neptune is the eighth and most distant planet in our solar system.

Most recently, the Voyager spacecrafts (visiting in 1980-81) made discoveries about the composition and interaction of the rings. Click to continue learning about ...Saturn - Rings, Atmosphere, Moons: Viewed from Earth, Saturn has an overall hazy yellow-brown appearance. The surface that is seen through telescopes and in spacecraft images is actually a complex of cloud layers decorated by many small-scale features, such as red, brown, and white spots, bands, eddies, and vortices, that vary over a fairly short time. In this way Saturn resembles a blander ...The two largest planets, Jupiter and Saturn, have nearly the same chemical makeup as the Sun; they are composed primarily of the two elements hydrogen and ...
