Jupiter's atmosphere is primarily composed of hydrogen and helium, but it also contains trace amounts of methane, ammonia, water vapor, and other gases. Overall, Jupiter's atmosphere is made up of at least 24 different gases.
Hydrogen and helium make up 99 percent of Jupiter's atmosphere. These two gases are the most abundant elements in the planet's composition.
carbon dioxide and nitrogen
One main reason is the gravity a dense object like a terrestial planet has. As gravity depends on the density of a object and a rocky planet has much density...our earth is the densest object in the solar system but Jupiter's gravity is more as gravity depends upon size too. The gravity holds the gases forming the atmosphere. Another reason is the core which has a magnetic effect and forms a magnetic layer which has some effect on the atmospheric gases and saves it from going away to the space by attracting the gases towards the pole where the gravity is the highest.
Jupiter is the largest planet in the solar system.
Gas planets are those planets which are not made up of rocks or materials. They are composed of gases only. Eg- Jupiter
These gases are hydrogen and helium.
Jupiter's dominant gases are hydrogen and helium. These two elements make up the vast majority of the planet's atmosphere, with hydrogen accounting for about 75% and helium making up around 24%. There are also trace amounts of other gases such as water vapor, ammonia, and methane.
Planet Mars has two moons
Jupiter is the largest planet in our solar system, and it has 63 known moons.
jupiter has hydrogen hulium and -o- and it also has aliens with heads the size of basketballs and they are green and -a-ra- is a alien with a green head so is -o- Penut Butter Jelly Time, PPPPPPPPPPPPPPPPPPPEEEEEEEEEEEEENNNNNNNNNNNNNNNNNUUUUUUUUUUUUUUTTTTTTTTTTTTTTTTTTTTTTTTTTJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJJEEEEEEEEEEEEEEEEEEEEEEEEEEELLLLLLLLLLLLLLLLLLLLLLLLLLLLL<LLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY TTTTTTTTTTTTTTTTTTTTTTTTTTTIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIMMMMMMMMMMMMMMMMMMMMMMEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE1!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1
