What are 4 characteristics of the inner planets?
The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings.
What are 3 facts about inner planets?
The inner planets have no rings circling them and zero to a few moons. Earth has one moon, and Mars has two. Mercury and Venus do not have any moons. Mars, Earth and Venus have atmospheres that are able to generate weather.
How can you describe the inner planets?
Definition: The inner planets are the four planets which orbit closest to the sun in our solar system. All of them are solid, rocky planets. The nearest to the sun is Mercury, followed by Venus, Earth and Mars.
What are the common characteristics of inner and outer planets?
1 Answer. Patrick H. Besides all of them being planets, all follow an elliptical orbit, all are spherical, and all are made of iron and nickel to some degree.
What are 5 characteristics of the inner planets?
All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.
What is difference 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.
How are the inner planets different than 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 (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
What are inner planets made of?
Every inner planet has a core. The cores of Mercury, Venus, and Earth are composed of iron-nickel. Mars's core is made of liquid iron sulfide mixed with some nickel….Structure.

What is not a characteristic of inner planets?
None of the inner planets have rings, while all of the outer planets have quite a few (rings are made up of small particles, possibly ice, that circle the outer planets). Inner planets have a paucity of moons, with Mars claiming two and Earth just one. Mercury and Venus have none.
What is not a characteristic of the inner planets?
None of the inner planets have rings, while all of the outer planets have quite a few (rings are made up of small particles, possibly ice, that circle the outer planets). Inner planets have a paucity of moons, with Mars claiming two and Earth just one. Mercury and Venus have none.
Do inner planets have moons?
Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons. In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons.
How are the inner planets different from 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 (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
Are inner planets more dense?
The giant planets are less dense overall because they are made mainly of gases, and the inner rocky planets are more dense because they are made mainly of rock.
Do inner planets have fast rotations?
The orbits of Mercury, Venus, Earth, and Mars revolve faster than the outer planets because they have less distance to travel. They revolve around the Sun all within a relatively flat plane.
What are 5 differences between inner and outer planets?
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).
Are inner planets made of gas?
The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K.
How do the inner planets differ from 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 (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
How do the inner planets move?
The Sun's gravity holds the inner planets tightly as they revolve around the Sun. The orbits of Mercury, Venus, Earth, and Mars revolve faster than the outer planets because they have less distance to travel. They revolve around the Sun all within a relatively flat plane.
What are inner planets mostly made of?
So the inner solar system objects are made of iron, silicon, magnesium, sulfer, aluminum, calcium and nickel. Many of these were present in compounds with oxygen. There were relatively few elements of any other kind in a solid state to form the inner planets.
Why are the inner planets different from the outer planets quizlet?
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. Inner planets have most of their atmospheres burned away by sun.
How do inner planets differ from 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.
How do the outer planets differ most from the inner planets?
The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer 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.
What do all of the inner planets have in common?
All of the inner planets are solid dense rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets the inner planets have shorter orbits around the Sun but all the inner planets spin more slowly.
How are the inner planets differ?

How do inner planets differ from outer?
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.
