what is the difference between the inner planets and the outer planets?

The Inner and Outer Planets in Our Solar System. ... 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 inner planets are much smaller than the outer planets and because of this have relatively low gravity and were not able to attract large amounts of gas to their atmospheres.

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 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 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.

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 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.

Astronomers call them the “terrestrial planets” because they have solid, rocky surfaces roughly similar to desert and mountainous areas on the earth. The inner planets are much smaller than Jupiter, Saturn, Uranus and Neptune, and they all possess iron cores.

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.

Outers-pace is SPACE, the void out there, between the planets, and beyond the solar system. There is no such thing as innerspace. Some may consider the space within an atom as inner-space. ... So, at least from my perspective, “outer-space” is the Universe out there, and “inner-space” is the Universe within us.

The main difference between stars and planets is that stars have high temperatures compared to planets. ... Because they radiate energy, stars are very bright objects. Planets do not generate their own energy through nuclear reactions. They reflect some of the radiation coming from their parent star.

How do the inner planets differ from the outer planets? ... Inner planets are smaller than the outer planets; gas giants have more gravity; Farther apart, inner planets have a solid surface, Inner planets are hotter, inner planets have a shorter period of revolution. Distance from the sun causes these differences.

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 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.

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.

The four inner planets, or terrestrial planets, have solid, rocky surfaces. Mercury is the smallest planet and the closest to the Sun. It has an extremely thin atmosphere, with surface temperatures ranging from very hot to very cold.

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.
