In order for gas to leave a planet it needs to be hot enough and to overcome the planet's gravity. The outer planets are colder and are very massive in comparison to Earth.
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.
Yes, outer planets like Jupiter and Saturn likely lost light gases from their atmospheres due to their gravity not being strong enough to retain these gases. Additionally, the strong solar wind and radiation in the outer solar system may have contributed to the loss of these gases over time.
The inner planets, such as Mercury, Venus, Earth, and Mars, are rocky and dense, with solid surfaces. They are located closer to the Sun where higher temperatures prevented light gases from accumulating. In contrast, the outer planets, like Jupiter, Saturn, Uranus, and Neptune, are gas giants composed mostly of hydrogen and helium. They are much further from the Sun, allowing them to accumulate these light gases and form large, gaseous atmospheres.
The planets with atmospheres so dense that one cannot see through them with a telescope are Venus and Titan, the largest moon of Saturn. These thick atmospheres are composed of gases and haze that block visible light from passing through, making it impossible to see the surface using traditional telescopes.
The Sun is a star, while planets are celestial bodies that orbit around stars. The Sun is much larger and emits light and heat through nuclear fusion reactions in its core, while planets do not produce their own light and instead reflect light from the Sun. Additionally, planets have distinct characteristics such as solid surfaces and atmospheres, unlike the Sun which is composed primarily of gases.
Gas giants like Jupiter and Saturn have thick atmospheres because they are predominantly made up of hydrogen and helium gases. The strong gravitational pull of these planets allows them to retain these light gases, forming thick atmospheres. Additionally, their atmospheres may also contain other elements and compounds that contribute to their composition and density.
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
Yes, outer planets like Jupiter and Saturn likely lost light gases from their atmospheres due to their gravity not being strong enough to retain these gases. Additionally, the strong solar wind and radiation in the outer solar system may have contributed to the loss of these gases over time.
Stars do not normally have atmospheres, some planets do
In general, planets don't make their own light. Rather, they reflect the light of the sun. It is possible to see lightning in the atmospheres of some planets, but that probably doesn't count.

Different planets have different atmospheres due to variations in their composition and distance from the sun. Factors like the planet's size, gravity, and proximity to the sun determine what gases are retained in the atmosphere, leading to unique compositions. Active processes like volcanic activity and biological activity can also contribute to the diversity of atmospheric compositions across planets.

Uranus
Gas giants like Jupiter and Saturn were formed by accumulating hydrogen and helium blown away from the early Sun. These planets have mostly light gases in their composition due to their formation process.
