what are similarities and differences between inner and outer planets?

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.

1 Answer. Inner planets have solid rocky cores, outer planets are mostly gas. Similar in that they are all part of our solar system.

Sometimes, planets in our solar system are classified with their position relative to the asteroid belt, which lies approximately between Mars and Jupiter. With this scenario, "inner" planets are Mercury, Venus, Earth and Mars. "Outer" planets are Jupiter, Saturn, Uranus and Neptune.

The inner planets of our solar system, Mercury, Venus, Earth, and Mars, originated from small dust and larger particles in the solar nebula that collided with each other over millions of years forming larger and larger particles (Figure 1a). These eventually became protoplanets.

Differences between the Inner and Outer Planets. ... The four planets closest to the Sun are known as the Inner Planets, or the Terrestrial Planets. These planets are Mercury, Earth, Venus and Mars. The four planets furthest from the Sun are known as the Outer Planets, or the Gas Giants.

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 inner planets, or terrestrial planets, are the four planets closest to the Sun: Mercury, Venus, Earth, and Mars.

Mercury, Venus, Earth, and Mars are the planets closest to the Sun. They are called the inner planets. The inner planets are made up mostly of rock.

Really, the only thing that the inner and outer planets have in common is that they are classified as planets. More specifically, they orbit the sun, they are large enough to have become more or less spherical, and they are the gravitationally dominant body in their orbit (i.e. they have “cleared” their orbit).

We tend to lump Uranus and Neptune together in our thoughts, almost as if they're twin worlds. They are nearly the same size – bigger than Earth, but smaller than Jupiter or Saturn – and both are bluish or bluish-green, with deep atmospheres and icy interiors.

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..

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.

The only difference between a planet and a dwarf planet is the area surrounding each celestial body. A dwarf planet has not cleared the area around its orbit, while a planet has. Since the new definition, three objects in our solar system have been classified as dwarf planets: Pluto, Ceres and Eris.

The four outer planets of the Solar System are gas giants. They share some atmospheric commonalities. All have atmospheres that are mostly hydrogen and helium and that blend into the liquid interior at pressures greater than the critical pressure, so that there is no clear boundary between atmosphere and body.

Our solar system includes the sun and eight planets that orbit around the sun. The smaller, inner planets include Mercury, Venus, Earth, and Mars. The inner planets are rocky and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune.

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 two planets have been scaled to the same size for the purpose of the comparison. The inner parts of the ring systems are very different: Saturn's is broad and opaque, while Uranus' inner rings are very narrow. ... Saturn's blue E ring is thought to come from a moon, Enceladus, buried within it.
