Its atmosphere is mainly made up of carbon dioxide (96%) and nitrogen (3%), with small amounts of other gases.
WebOct 17, 2024 · The composition of Jupiter is similar to that of the Sun – mostly hydrogen and helium. Deep in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid. This gives Jupiter the largest ocean in the solar system – an ocean made of hydrogen instead of water. WebInteresting Terrestrial Planets Facts. From largest to smallest, the terrestrial planets are Earth, Venus, Mars, and Mercury. Earth is roughly 12,756 km (7,926 miles) across while Venus is 12,104 km (7,521 miles) across. They are often called “sister planets” because of their similar sizes.
