Solar System – Introduction

The solar system is the gravitationally bound system where objects orbit around the sun, directly or indirectly. Directly like the planets and indirectly like the moons.

In the beginning we did no recognize the concept of the solar system. Most of the people believed that Earth is the center of the universe. In 17th century Galileo Galilei, Johannes Kepler and Issac Newton developed an understanding concept and understand that planets move around the sun.

Solar System


The Solar system formed almost 4.6 billion years ago due to gravitational collapse of a giant interstellar cloud. The vast majority of the system’s mass is in the sun and most of the remaining mass is in the Jupiter.

The solar system contains smaller objects like Asteroids belt. Asteroid belt lies between the orbit of Mars and the Jupiter which contains object rock and metal. Kuiper belt beyond Neptune’s orbit which are population of trans-Neptunian objects which which composed most of the ice. It is called dwarf planets like Pluto and Eris. Six of the planets which orbited by natural satellites which called moons after the moon. The outer planets encircled by rings which made of dust and other small objects.

The solar system is located in the Orion Arm which is 26,000 light years away from the center of the Milky Way.
