How are the inner and outer planets similar and different?
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 and outer planets differ and composition?
The inner planets are made of rocky material, which has higher density; these are often known as terrestrial (earth-like) planets. The outer planets are made mostly of low density gases; these are often known as Jovian (Jupiter-like) planets.
What materials compose inner and outer planets?
The planets are of two different types. The four inner planets, those closest to the Sun, are Mercury, Venus, Earth, and Mars. They are smaller and composed mainly of metals and rocks. The four outer planets — Jupiter, Saturn, Uranus, and Neptune — are larger and composed mostly of gases.
What is the similarities of inner planets and outer planets?
Inner planets have solid rocky cores, outer planets are mostly gas. Similar in that they are all part of our solar system.
What similarities do inner and outer planets have in common?
The Inner and Outer planets have many things in common. They both orbit around a star. In this case the star they orbit is the Sun. All eight planets are round which make them similar.
How are the inner planets similar?
The Inner Planets They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small.
What do the inner planets have in common?
What are the characteristics of inner and outer 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 are the similarities of the outer planets?
The four outer planets are all gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. The outer planets have numerous moons, as well as planetary rings.
What do inner planets have in common?
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.
What are the similarities between the inner planets?
The four inner planets — Mercury, Venus, Earth and Mars — share several features in common. Astronomers call them the “terrestrial planets” because they have solid, rocky surfaces roughly similar to desert and mountainous areas on the earth.
