Detailed explanation-2: -Unlike the terrestrial planets that make up our inner solar system-Mercury, Venus, Earth, and Mars-the Jovian planets do not have solid surfaces. Instead, they are composed primarily of hydrogen and helium, with traces of methane, ammonia, water, and other gases in their atmospheres.
