what are the main differences between the inner and outer planets?

In our Solar System, astronomers often divide the planets into two groups — the inner planets and the outer planets. The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas.

The outer four planets (Jupiter, Saturn, Uranus, and Neptune) were able to keep their original atmospheres. They have very thick atmospheres with proportionally small solid cores while the the inner four planets have thin atmospheres with proportionally large solid parts.

Orbiting the Sun are eight planets. The four planets closest to the Sun are known as the Inner Planets, or the Terrestrial Planets. ... Separating the Inner Planets from the Outer Planets is the Asteroid Belt, a region of thousands of asteroids in orbit of the Sun between Mars and Jupiter.

The innermost planets are rocky and consist of Mercury, Venus, Earth, and Mars. The much larger outer planets are the giant gas planets and consist of Jupiter, Saturn, Uranus and Neptune. Most of the planets have moons, and most of the moons are tiny compaired tot he planet they are in orbit around.

1) The “inner planets” (Mercury, Venus, Earth, Mars) don't have rings and all of the “outer planets” (Jupiter, Saturn, Uranus, and Neptune) do. 2) The outer planets are much more massive than the inner planets. ... When they are in the gravity well of an outer planet, like Saturn, they start to orbit the planet.

The planets are all rotating around their own axis, as they revolve around the Sun. The planets are divided into inner and outer planets. The inner planets are all composed of "rock," just like the Earth. The outer planets, except for Pluto, are composed of gas.

Gas giants/Jovian planets are also called the outer planets, they are made of gases, they are large and less dense, more moons. Terrestrial/Rocky planets are also called the inner planets. They are made of rocky surface, denser than Jovians, and small, little or no moons.

The main difference between stars and planets is that stars have high temperatures compared to planets. Stars undergo nuclear reactions—they burn hydrogen in their cores, releasing massive amounts of energy. In order to be hot enough for these reactions to take place, stars need to be extremely big.

They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune. Jupiter, Saturn, Uranus, and Neptune are large balls of gases with rings around them.

The Inner and Outer Planets in Our Solar System. ... The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.

The four inner planets, or terrestrial planets, have solid, rocky surfaces. Earth, the third planet from the Sun, is the only planet with large amounts of liquid water, and the only planet known to support life.

As their name suggests, the main difference between a dwarf planet and a planet is size. Because they are smaller, dwarf planets lack the gravitational forces needed to pull in and accumulate all of the material found in their orbits. Each known dwarf planet in our solar system is actually smaller than Earth's Moon!

The inner planets are closer to the Sun and are smaller and rockier. ... The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.

The outer planets are also called the Jovian planets or gas giants. Like the inner planets, the outer planets have similar characteristics to one another. The outer planets are so much larger than the inner planets that they make up 99 percent of the mass of the celestial bodies that orbit the Sun.

One of the main differences that can be seen between terrestrial and jovian planets, is their surfaces. While the terrestrial planets are made of solid surfaces, the jovian planets are made of gaseous surfaces.

They both have gas giants and they're both planets in our Solar System. Jupiter is different from Saturn in many ways, Jupiter has a great big red spot and brighter colored bands. Jupiter also has 16 moons and hurricane force winds. Saturn has duller colored bands and many moons.

The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. ... In the outer regions of the solar system where it was cooler, other elements like water and methane did not vaporize and were able to form the giant planets.
