The document summarizes the two main types of planets in our solar system - the terrestrial and Jovian planets. It describes the terrestrial planets as Mercury, Venus, Earth and Mars - rocky bodies close to the Sun. It then explains the Jovian planets - Jupiter, Saturn, Uranus and Neptune - as large gas giants farther from the Sun. Diagrams are included showing the approximate distances of each planetary group from the Sun.

3. The Terrestrial Planets
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. The following diagram shows the approximate distance of
the terrestrial planets to the Sun.
5. The Jovian Planets
Jupiter, Saturn, Uranus, and Neptune are known as the Jovian (Jupiter-like)
planets, because they are all gigantic compared with Earth, and they have a
gaseous nature like Jupiter's. The Jovian planets are also referred to as the gas
giants, although some or all of them might have small solid cores. The following
diagram shows the approximate distance of the Jovian planets to the Sun.
