The planets that were formed by light gases are called terrestrial planets, also known as the gas giants.
The gas giants are:
I think the question is probably about "light elements".The inner planets are relatively warm and small. This means they have notbeen able to keep the lightest elements, hydrogen and helium, as gases.
The Sun is a star that emits light and heat through nuclear fusion, providing energy for life on Earth. Other planets do not have this capability and only reflect light from the Sun. The Moon is a satellite that reflects sunlight but does not produce its own light.
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
no planets crust does not have light of their own but the core of the earth has light of its own
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.
Uranus
Uranus was formed from the light gases of the outer solar nebula.
Gas giants like Jupiter and Saturn were formed from the light gases of the outer solar nebula. Their composition is primarily hydrogen and helium, with traces of other gases.
Uranus
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.
I think the question is probably about "light elements".The inner planets are relatively warm and small. This means they have notbeen able to keep the lightest elements, hydrogen and helium, as gases.
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.
The Sun is a star that emits light and heat through nuclear fusion, providing energy for life on Earth. Other planets do not have this capability and only reflect light from the Sun. The Moon is a satellite that reflects sunlight but does not produce its own light.
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.
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
No, planets don't give off light, stars did.
It has no "job" really as it simply a collection of burning light gases pulled together with a few other things sometimes thrown in. The mass of this burning gases creates orbits where heavier colder substances to get trapped in creating planets. The star then heats and provides light for planets created. When the right chemicals came together you got the earth and its ecosystem developing.
