Heavenly Bodies Around Us
The universe has many galaxies with different shapes. A galaxy is a group of stars that are bound by the force of gravity. The galaxy consists of many planets that surround it. The Milky Way Galaxy is a galaxy where humans live. The Milky Way galaxy is a spiral. In it there are very many celestial bodies.
In the Milky Way galaxy there is our solar system. Our Solar System consists of eight planets that circle the Sun. Apart from planets and the Sun, the solar system also consists of satellites, asteroids and comets. Let’s take a closer look at our solar system.
Every planet in the solar system is on an elliptical orbit called an orbit. As long as they remain in their orbits, the Planets do not collide with each other. The planets that circle the Sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
Each planet rotates on its axis. The event that a planet rotates on its axis is called rotation. Earth’s rotation causes us to experience day and night events alternately. All the planets in the solar system will revolve around the sun. Therefore, the Sun is called the center of the solar system. The event that the planet rotates around the sun is called a revolution.
Each planet has a different time to circle the Sun in one complete rotation. Earth’s rotation causes changes of day and night.
