Do you know that inner and outer planets have different traits? This is why years are different for the Inner and Outer planets. The inner planets are all smaller and denser than the outer planets. Since they are mostly made of gases, they are also called gas giants.Pictured below are the relative sizes of the outer planets and the Sun (Figure below) This, in turn, is affected by the temperature. In contrast, the core of the outer planets is ice. They all also have planetary rings, composed of dust and other small particles that encircle the planet in a thin plane. We have moved all content for this concept to for better organization. The Inner have small amounts of moons, while the Outer have many moons. The inner and outer planets are separated by asteroid belt. Compares the characteristics of inner and outer planets. While inner planets are rocky, relatively small and relatively warm, mostly with an atmosphere and without moons or planets, the outer planets are completely opposite – they’re very large and massive, either gaseous or icy, mostly composed of … In fact, the radius of the entire region is less than … The composition of planets is affected by the availability of elements around them. Inner and Outer Planets What’s the Difference?? The inner planets are also called telluric since their nucleus is very hot. Please update your bookmarks accordingly. These are the four planets farthest from the Sun.The outer planets are much larger than the inner planets. Let the Electric Socketz charge up your knowledge! The hotter it is, the more elements melt and the faster gas molecules move. The outer planets have rings and many satellites and moons, unlike the inner planets that do not have rings and have few satellites. For example Jupiter has more than 60 moons including the four largest, the Galilean Moons. The four outer planets, or giant planets (sometimes called Jovian planets), collectively make up 99% of the mass known to orbit the Sun. Another difference is that Outer planets have rings, and Inner planets do not. Name:_ /26 Date:_ The Solar System: Inner and outer planets Mr. Inskip 1) In what two groups View The Solar System_ Inner and outer planets.docx.pdf from SCIENCE OF 1010 at University of Lethbridge. Jupiter, Saturn, Uranus, and Neptune are the outer planets of our solar system. The Inner planets orbit the Sun quickly, while the Outer orbit slowly. Jupiter and Saturn are together more than 400 times the mass of Earth and consist overwhelmingly of the gases hydrogen and helium, hence their designation as gas giants. The inner planets are also much more closely spaced than their outer Solar System counterparts. I tell the students that in fact, all the outer planets have rings, Saturn is the only one you can see with a telescope but they do all have rings. They are mostly solid and composed of rock rather than gas. The outer planets are larger then the inner planets, and one student says that Saturn has rings.
