What is the difference between other planets and inner planets

Apr 11, What was a major difference in the formation of the inner and outer planets? The elements in the Inner Planets are more closely packed together, causing them to be smaller and solid. Despite being larger, the elements that make up the Outer Planets are less densely packed together causing them to be quite light for their size.

Summary The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants. Aug 2, The four outer planets are all gas giants made primarily of hydrogen and helium.

They have thick gaseous outer layers and liquid interiors. The outer planets have numerous moons, as well as planetary rings. The inner planets, or terrestrial planets, are the four planets closest to the Sun: Mercury, Venus, Earth, and Mars. Figure below shows the relative sizes of these four inner planets. This composite shows the relative sizes of the four inner planets. From left to right, they are Mercury, Venus, Earth, and Mars. Sep 14, All of the inner planets are solid, dense, rocky planets.

The inner planets either do not have moons or have just one Earth or two Mars. None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly. Astronomers theorize that the very early solar system formed as a ring of materials surrounding the sun.

Size Range. Rocky Surface. Iron Core. They have very cold temperatures. All of the planets in the solar system rotate and orbit the sun. The planets are alike because all the planets are made up of the same things like rocks and ice.

Inner planets [Mercury, Mars, Venus, and Earth] are all close to the sun, so they are warmer than the outer planets. Mercury Mercury. Mercury—the smallest planet in our solar system and closest to the Sun—is only slightly larger than Earth's Moon. Mercury is the fastest planet, zipping around the Sun every 88 Earth days. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune.

These four large planets, also called jovian planets after Jupiter, reside in the outer part of the solar system past the orbits of Mars and the asteroid belt. Mar 30, Venus Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system's hottest planet. Jan 30, The gas giants have atmospheres that are mostly hydrogen and helium.

All four planets rotate relatively rapidly — while Earth spins once on its axis every 24 hours, Saturn spins once every 10 hours. Like Earth, all the gas giants have wind bands. These are seen as east-west stripes. Uranus With a temperature of degrees Fahrenheit, Uranus is the coldest planet in the solar system.

The outer planets are also called the Jovian planets or gas giants. Jun 24, The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. Oct 10, A region between Mars and Jupiter became the asteroid belt. Occasionally people wonder whether the belt was made up of the remains of a destroyed planet, or a world that didn't quite get started.

However, according to NASA, the total mass of the belt is less than the moon, far too small to weigh in as a planet. The outer planets of our Solar System i. Jovian planets — namely Jupiter, Saturn, Uranus, and Neptune — are the planets that lie farthest from the sun. The inner planets are believed to have come from materials from a collapsed nebula that formed near the sun. Rocks, heavy metals, and other solid materials make up the composition of these inner planets.

Other materials such as gas that was swept halfway across the Solar System formed the outer planets. This is the main reason outer planets are mostly made up of gases such as helium hydrogen, and methane. By: Editorial Staff Updated: Dec-4, Did this article help you? Yes No. Current rating: 8.

Thank you! What was wrong? The facts are wrong. Want more images. Article is outdated. Most of the material accumulated at its center to form the sun.

The rest of the matter continued to contract while rotating and flattened into a disk called protoplanetary disk. The heavy rocky particles within the inner part of the disk formed planetesimals and eventually, inner planets.

In our solar system, the four innermost planets Mercury, Venus, Earth and Mars are known as inner planets.

They lie inside the asteroid belt. They have volcanoes and valleys and are very hot compared to outer planets. The first two planets Mercury and Venus have no moons whereas one moon orbits the third planet earth. Mars, the outermost inner planet has two natural satellites or moons. Earth is the dominating planet out of four inner planets, and all of the inner planets are nearly similar in size and composition.

Therefore, sometimes the four inner planets are also referred to as earth- like planets. The light gases and ices within the outer part of the protoplanetary disk attracted and stuck together forming large celestial bodies.

Eventually, they collided together and merged into massive gas giants called outer planets. All of these planets lie beyond the asteroid belt. There are four outer planets in our solar system namely Jupiter, Saturn, Uranus, and Neptune. They are large in size compared to inner planets. Jupiter is the largest outer planet whereas Uranus is the smallest.

All the outer planets have a lot of moons and thin ring systems made of dust and rocks. Their thick atmospheres consist mostly of Hydrogen and Helium. They are very cold as they are far away from the sun.
