The Outer Planets
The next four planets out from the sun are Jupiter,
Saturn, Uranus, and Neptune. They are collectively
referred to as the Jovian planets (means Jupiter like).
They are significantly different from the terrestrial
planets. Besides being farther from the sun, the Jovian
planets are much larger, are more gaseous, have lower
densities, and all have some sort of rings. Their large
sizes are responsible for increased gravity which can
hold onto lighter elements like gases.
A belt of asteroids (fragments of rock and iron) between
Mars and Jupiter separate the four inner planets from
the five outer planets.
