Passage:
The Solar System
Our solar system is made up of the sun and all the objects that orbit around it. There are eight planets in our solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These planets are divided into two groups: the inner planets and the outer planets.
The inner planets are the four planets closest to the sun: Mercury, Venus, Earth, and Mars. They are called the inner planets because they are located inside the asteroid belt, a region of space filled with small rocky objects. The inner planets are made mostly of rock and metal.
The outer planets are the four planets farthest from the sun: Jupiter, Saturn, Uranus, and Neptune. They are called the outer planets because they are located outside the asteroid belt. The outer planets are made mostly of gas and are much larger than the inner planets.
In addition to the planets, our solar system also includes other objects such as moons, asteroids, and comets. Moons are natural satellites that orbit around planets. Asteroids are rocky objects that orbit the sun, and comets are made up of ice, dust, and gas.
Our solar system is a fascinating place with many different objects to explore. Scientists continue to study and learn more about the solar system every day.
