The four outer planets consist of mainly gas, according to Northern Virginia Community College. These gas giants do not have a solid surface. Jupiter is the closest outer planet. The large red spot on Jupiter is actually a several hundred year old storm. Saturn is the sixth planet, and it is famous for the icy rings that surround it. Saturn has 52 moons, and the moon Titan even has its own atmosphere. Uranus contains methane gas, hydrogen and helium. Its enormous amount of ice gives it the name of ice giant. Less famously, Uranus has small rings around the planet, which consists of dust instead of ice. Neptune is the farthest planet from the sun, and, like Uranus, it is also largely ice with methane gas. Pluto is a dwarf planet in the same area as the Kuiper Belt, which is home to many icy comets, according to the National Aeronautics and Space Administration.

The Asteroid Belt separates the inner planets from the outer planets, according to the National Aeronautics and Space Administration. The outer planets are farther away from the sun, explaining the planets' colder temperatures and longer orbits around the Sun.

  • Q:

    How far are the planets from the sun?

    A:

    The eight described planets all orbit the Sun at different distances; Mercury is the closest planet to the sun, followed by Venus, then Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The distances of the planets are normally measured in kilometers, because scientists use metric measurements. However, scientists also use a unit called an “astronomical unit,” which is equal to the distance between Earth and the sun.
