Terrestrial Planet Sizes

The terrestrial planets are the four innermost planets in the solar system; Mercury, Venus, Earth, and Mars. They are called terrestrial because they have a compact, rocky surface like the Earth's. The planets Venus, Earth, and Mars have significant atmospheres, while Mercury has almost none. This diagram shows the approximate relative sizes of the terrestrial planets. Distances are not to scale.
