what are three differences between inner and 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 inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.

Each one is different, yet they are all very similar. The different features consist of size, amount of moons, rings, and orbit speed. They are the same, however, because they all orbit the sun, have a core, are round, and have gravity. The planets are truly amazing things in space.

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. Earth has a large round moon. Mercury is the smallest planet and is the closest to the Sun.

Most of the Outer Planets are made of gas. ... The contents of the atmospheres of the Inner Planets varies from planet to planet. Mercury has no atmosphere although Sodium and Helium can be detected above the surface. Venus' atmosphere is mostly Carbon Dioxide with a very small amount of Nitrogen.

| NASA (from left: Mercury, Venus, Earth, and Mars) The Inner Planets. The four innermost planets in the Solar System (Mercury, Venus, Earth, and Mars) are sometimes called the "terrestrial" planets because of their proximity to Earth ("Terra" in Latin) and their similarity as compact solid bodies with rocky surfaces.

The four planets farthest from the Sun are the outer planets. ... Since the inner planets didn't have enough mass to hold on to these light gases, their hydrogen and helium floated away into space. The Sun and the massive outer planets had enough gravity to keep hydrogen and helium from drifting away.

The Inner and Outer Planets in Our Solar System. ... The outer planets are further away, larger and made up mostly of gas. 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 These planets are much larger than the inner planets and are made primarily of gases and liquids, so they are also called gas giants. This image shows the four outer planets and the Sun, with sizes to scale. From left to right, the outer planets are Jupiter, Saturn, Uranus, and Neptune.

Inner planets have fewer moons, small, silicate surface, nickel-iron core, higher density and rotate more slowly compared to outer planets. Outer planets have a greater number of moons, no solid part; rotate faster, have a lower density as well as rings in some cases (Jupiter and Saturn).

The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials.

What differentiates terrestrial planets from Jovian planets? Terrestrial planets are smaller, denser, and closer to the Sun than Jovian planets, which are larger, less dense, and farther from the Sun.
