['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.']

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).

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. ... While the inner planets have few or no moons, the outer planets have dozens each.

The Solar System may be divided by its components into three major regions: the inner system, the near outer system, and the far outer system.

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.

Main Difference: The main difference between the inner core and outer core of the earth is that inner core of the earth is the innermost layer of our planet, whereas outer core is the layer that surrounds the inner core.

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 inner planets of the solar system are mercury ,venus ,earth and mars. whereas the outer planets are jupiter saturn uranus and neptune.. they differ from each other according to their size. the inner planets are before the asteroids and the outer planets are after the asteroid belt..

['Terrestrial Planets. Mercury, Venus, Earth, Mars (Inner Planets) Small (about the size of the Earth) Rocky, usually with large iron cores. ... ', "Jovian Planets. Jupiter, Saturn, Uranus, Neptune (Outer Planets) Large (about 10 times the size of the Earth) No solid surface -- ``Gas Giants''"]

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 outer planets are further away, larger and made up mostly of gas. ... After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune.

The four planets closest to the Sun—Mercury, Venus, Earth, and Mars—are the inner planets or terrestrial planets (Figure below). They are similar to Earth. All are solid, dense, and rocky.

Like the Inner Planets, the Outer Planets share similarities but each also has its own unique characteristics. As well as all being huge and being made up mostly of gases, all four have rings spinning around them, with Saturn having the most famous rings. All four planets also have large numbers of moons orbiting them.

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.

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.

In our Solar System, astronomers often divide the planets into two groups — the inner planets and the outer planets. ... 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.
