They are are not similar.
A gas giant is similar in composition to the Sun. The Sun is much bigger than the gas giants and it is a star not a planet, of course.
All of the gas giant planets are similar: Jupiter, Saturn, Uranus, and Neptune. They differ mainly in size and the concentration of certain gases in their atmospheres.
Well, the inner planets are not made up of gas like Saturn and Jupiter but Neptune and Uranus are surrounded by the gas giant
The gas giant planets have stronger gravity, which makes it harder for anything to escape, and are colder, which means that even with similar gravitational fields, gas molecules might not achieve escape velocity.
No. Mars is a rocky planet, similar to earth in some ways. We are attempting at this very moment to determine if there was ever life on Mars, or if Mars could possibly sustain life in the future.
