COMPOSITION AND FUNCTION OF THE SOLAR SYSTEM

Have you carefully observed the sun, moon and other space objects that are visible in the sky?

There is evidence that man has been interested in these objects since very early times.  Scientific advances have made modern instruments necessary for sky observation.  Therefore, man can explore much more than what the naked eye can see.

It has already been discovered that eight planets are orbiting a massive star called the sun, fragments of asteroid known as asteroids, and a variety of space objects, such as dwarf planets and sub-planets.

Taken together, all of these orbits around the sun can be called a system.  This system is known as the Solar System.  The Solar System is believed to have formed from the merger of dust and air particles that existed about 4600 million years ago.

By observing the night sky, a large number of stars are visible to the naked eye.  Stars are space objects that have an energy source that releases light and heat.  They are bright and shiny.

Other planets do not emit light but reflect the view from the sun.  Therefore, the planets appear in the sky with a uniform light without shining.

Composition of the Solar System

The solar system and the other Celestial objects of the Solar System belong to the Solar System.
