What is the diameter of the inner planets?
The inner planets are rocky and have diameters of less than 13,000 kilometers. The outer planets include Jupiter, Saturn, Uranus, and Neptune. The outer planets are called gas giants and have a diameter of greater than 48,000 kilometers.
What is the relationship of the distance of the inner planets?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
Is there a connection between diameter and the distance a planet is from the sun?
There is no connection between a planet’s distance from the Sun and its rate of rotation (spin on its own axis or Planetary Rotation Period).

What do you know about the inner planets?
The inner planets of the solar system are also called terrestrial planets, and include Mercury, Venus, Earth and Mars. They are mostly made up of silicate rock and metals and have solid surfaces. The inner planets orbit the closest to the Sun, and Earth is the only one with known life.
What is the distance between each planet and the Sun?
| Planet (or Dwarf Planet) | Distance from the Sun (Astronomical Units miles km) |
|---|---|
| Venus | 0.723 AU 67.2 million miles 108.2 million km |
| Earth | 1 AU 93 million miles 149.6 million km |
