By mass, the majority of the matter orbiting the sun is hydrogen and helium. When the solar system was just starting to form heat from the sun and the strong solar wind drove most of the hydrogen, helium, and other gasses out of the inner solar system, leaving behind mostly rock and metal, which were much less abundant. The sunlight and solar wind in the outer solar system were much less intense, so these gasses remained in place long enough to become part of the giant planets.
What else can I help you with?
What four inner planets are larger than the outer planets?
The inner planets are smaller than the outer planets.
Are the inner planets smaller than the outer planets?
Yes, the inner planets (Mercury, Venus, Earth, and Mars) are smaller than the outer planets (Jupiter, Saturn, Uranus, and Neptune). The outer planets are known as gas giants and are much larger in size compared to the inner terrestrial planets.
Are outer planets or inner planets larger?
The outer planets are larger.
Are outer planets larger and rockier than inner planets?
they are larger but not rockier then the inner planets the outer planets are made of gas.
Outer planets have smaller orbital periods than inner planets?
They are farther away and have larger orbital periods.
What 3 ways do inner planets differ from outer planets?
Inner planets are smaller and made of rock and metal, while outer planets are larger and predominantly made of gas and ice. Inner planets have few or no moons, while outer planets have numerous moons. Inner planets have solid surfaces, while outer planets do not have solid surfaces, instead having thick atmospheres.
Are the inner planets larger then the outer planets and are they made of gas?
No. The outer planets are larger and are mainly gaseous.
Why do you compare outer planets to inner planets?
Outer planets and inner planets are compared because they have distinct differences in size, composition, and characteristics. Inner planets are smaller, rocky, and denser, while outer planets are larger, gaseous, and have thick atmospheres. Studying these differences helps scientists understand how planets form and evolve in our solar system.
Are the inner and outer planets different?
The inner planets are all rocky planets. The outer planets are completely made up of gases. The inner planets are much smaller than the outer planets.
How are the inner and outer planets alike?
The inner and outer planets are alike in that they are all part of our solar system and orbit around the Sun. They also have varying sizes and compositions, with the inner planets being smaller and rocky while the outer planets are larger and gaseous. Additionally, they all have moons, but the outer planets tend to have more and larger moons compared to the inner planets.
Separates the inner planets from the outer planets?
The asteroid belt separates the inner planets (Mercury, Venus, Earth, and Mars) from the outer planets (Jupiter, Saturn, Uranus, and Neptune). The inner planets are smaller, denser, and rocky, while the outer planets are larger, gaseous, and have rings.
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.
