The four inner planets, also known as the terrestrial planets, are Mercury, Venus, Earth, and Mars. Among them, Mercury has almost no atmosphere due to its small size and proximity to the Sun, which causes any gases to escape easily. Mars has a thin atmosphere, primarily composed of carbon dioxide, but it is much less substantial than Earth's. Venus has a thick atmosphere, so it does not fit the criteria of having almost no atmosphere.
