If you are experiencing problems with the electrical system, the alternator itself might be fine because the problem could be with one of the belts connected to the alternator. By doing a visual inspection of the engine compartment, you can determine if a belt is too loose or too tight.
The inner planets are called inner planets because they are relatively near to the Sun, in the inner part of the Solar System. They are also called the rocky planets because they are mainly made of rocks. The outer planets are also called gas giants and are composed mostly of gases or liquefied gas.
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. Pluto, which fits in with neither the terrestrial or the Jovian planets, is actually considered a Kuiper Belt object which we will see in more depth on the Kuiper Belt page.
