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.

Did outer planets lose the light gases in their atmosphere?

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.


Why are inner planets of solar system different from outer planets?

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.


Which planets have atmospheres so dense that one cannot see through them with a telescope?

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.


Why is the sun different from other planets?

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.


Why do all of the gas planets have a thick atmosphere?

When our Solar System was still young the 8 planets were still being formed, Mercury, Venus, Earth, and Mars are rocky because they are closer to the sun so most of the gas surrounding the planets faded away, Since the gas planets are farther away from the Sun (Cooler) the planet's gasses didn't fade out.

Why have the Jovian planets retained their atmospheres?

Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.

What does a star's atmosphere do to some light?

Stars do not normally have atmospheres, some planets do


How do planets make their own light?

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.

Why do different planets have different atmospheres?

All the sun's planets probably had similar atmospheres when they first formed, billions of years ago. The most common gases were the light gases, hydrogen and helium, with smaller amounts of oxygen, nitrogen and other gases. The immense gravity of the giant planets, Jupiter, Saturn, Uranus and Neptune, was able to hold the hydrogen and helium, which remain the predominant gases in their atmospheres, along with methane formed by the combination of hydrogen with free carbon. However, hydrogen and helium gradually escaped from the atmospheres of the smaller planets, where gravity is insufficient to hold the light gases permanently. Even the heavier gases, such as oxygen and nitrogen, as well as carbon dioxide and water vapour, can gradually escape from smaller planets, such as Mars and Mercury. So, these planets now have quite thin atmospheres. The Moon and other small bodies in the solar system have essentially no atmosphere. In our solar system, only the Earth and Venus are the right size to lose most of the light gases, while retaining gases such as oxygen, nitrogen, carbon dioxide and water vapour.
