The outer planets.
The four inner planets (Mercury, Venus, Earth, Mars) are similar to Earth - relatively small, and with a rocky surface.
The four outer planets (Jupiter, Saturn, Uranos, Neptune) are gas giants - between 5 and 11 times the diameter of Earth, and made up mainly of gas. They don't have a solid surface you can step on - just gas that gets denser as you go deeper inside.
What else can I help you with?
Why are the outer planets less dense?
They are made of less dense materials. While the inner planets are made primarily of rock, the outer planets are made mostly of hydrogen and helium.
What sort of surfaces do the inner planets have?
The inner, or terrestrial planets are more dense than the outer planets/gas giants/jovian planets. Through a process of differentiation we find inner planets to typically consist of a molten iron core and a less dense silicate crust.
What are three ways that the inner planets are different from the putter planets?
The inner planets are rocky, with distinct solid surfaces, and dense, whereas the outer planets are gaseous, have no solid surface and are relatively light in comparison. The density of Saturn, for example, is less than that of water.
Why do inner planets have thinner atmospheres than the outer planets?
An atmosphere is a layer of gas that surrounds a planet; this gas is attracted by gravity and is greater in volume depending on the strength of the gravitational field and the temperature of the atmosphere. The inner planets generally have less mass, resulting in a less strong gravitational field, and a warmer atmosphere meaning the atmosphere is thinner than the colder, larger outer planets.
How do the distances between the inner planets compare to the distance between the outer planets?
The orbits of the four inner planets are much closer, all orbiting the sun within ¼ billion km. The outer planets are more spread out, but are much larger in size. Their distances roughly double each time as you go out from Jupiter. Average distances of inner planets from sun; Mercury, 57,909,175km Venus, 108,208,930km Earth, 149,597,890km Mars, 227,936,640km Average distances of outer planets from sun; Jupiter, 778,412,010km Saturn, 1,426,725,400km Uranus, 2,870,972,200km Neptune, 4,498,252,900km

Why are the outer planets less dense?
They are made of less dense materials. While the inner planets are made primarily of rock, the outer planets are made mostly of hydrogen and helium.
Are outer planets denser than smaller planets?
No. The outer planets are gas planets, which are much less dense than the inner terrestrial planets.
Are the outer planets lighter than the inner planets?
No, the outer planets are not lighter than the inner planets. In fact, the outer planets are generally much larger and more massive than the inner planets. This is because they are primarily composed of gases and ice, which makes them less dense but more massive.
What sort of surfaces do the inner planets have?
The inner, or terrestrial planets are more dense than the outer planets/gas giants/jovian planets. Through a process of differentiation we find inner planets to typically consist of a molten iron core and a less dense silicate crust.
How do the inner planets differ from the outer?
The inner planets are smaller, denser, and rocky, while the outer planets are larger, less dense, and composed mostly of gas. Inner planets are closer to the sun and have shorter orbits, while outer planets are farther away and have longer orbits. Additionally, inner planets have few or no moons, while outer planets have numerous moons.
Is the distance between inner planets less or greater than the distance between the outer planets?
The inner planets are closer together than the outer ones.
Is the distance between inner planets less than or greater than the distance between the outer planets?
The inner planets are closer together than the outer ones.
What is the least dense crust outer core mantle or the inner core?
The crust is the least dense. The inner core is the most dense. So from the middle outwards the layers get less and less dense

Why is the outer core above the inner core?
The outer core is less dense than the inner core, and therefore floats on top of it.
What is a inner planer?
An inner planet is mostly made of iron and has more mass than outer planets, outer planets are mostly made of gasses, makeing them have less mass. The inner planets are the planets between the asteroid belt and the sun
