Answer Key
In our solar system, there are eight planets that revolve around the Sun. The Earth is
unique because it has only one moon that orbits around it. The Earth revolves
around the star in our solar system called the Sun. The word orbit describes the
path that something takes when it moves in an oval or almost circular pattern. How
long do these orbits take? Do you think they’re all the same?
The planets are different in many ways, but they also have some similar properties
to one another. One similar property is that all of the planets orbit, or circle around,
the Sun. This path takes the planets different amounts of time depending on how
far, or distant, they are from the Sun. The outer planets such as Jupiter or Saturn
have a longer/larger orbit because they have farther to go to revolve around the
Sun.
All of our planets in our solar system revolve/orbit around the Sun. There are four
inner planets, including Mercury, which is closest to the Sun, followed by Venus,
Earth, and Mars. There are also four outer planets, consisting of Jupiter, Saturn,
which has rings, Uranus, and then farthest from the Sun is Neptune.
