hydrogen
Most of the outer planets, such as Jupiter and Saturn, contain hydrogen as the primary light element. Hydrogen is the most abundant element in the universe and makes up a significant portion of these gas giants' composition.
Outer planets like Jupiter and Saturn have stronger gravity due to their larger masses, which helps them retain light gases in their atmospheres. Additionally, the colder temperatures in the outer solar system reduce the speed of gas particles, making it more difficult for them to escape the planets' gravitational pull. These factors combined allow the outer planets to hold on to their light gases.
outer planets are gas giants whille inner planets are just rocky planets. that includes that outer planets have significant amount of mass than the inner planets
the outer planets are gaseous and the inner planets are not
The inner planets are closer together than the outer planets are.

An asteroid belt.

Hydrogen and Helium
Uranus
yes, however as compared to the outer planets, no.
The source of light in outer space varies. Light can be reflected off from the stars, moons, comets, asteroids and planets.
its not different at all they are just outer planets
helium and hydroen
The outer planets are larger.
Meteorites.
The inner planets Mercury, Venus, Earth and Mars are small, heavy and mostly made of rock. The outer planets Jupiter, Saturn, Uranus and Neptune are huge, light and mostly made of gas.
