There are 10 lessons in this physics tutorial covering Sun and Planetary Motion. The tutorial starts with an introduction to Sun and Planetary Motion and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific physics lesson as required to build your physics knowledge of Sun and Planetary Motion. you can access all the lessons from this tutorial below.

In this Physics tutorial, you will learn:

  • What are some basic features of the Sun (mass, radius, position)?
  • Why is Sun the main source of energy for Solar System?
  • How the solar energy is produced?
  • How energy transmission does occur in different layers of the Sun?
  • What is the structure of Sun? What features does each layer present?
  • What are solar protuberances?
  • What laws the planetary motion around the Sun does follow?
  • What is sidereal and tropical period?
  • What is ecliptics and ecliptic plane?
  • What are inner and outer planet? How does the observation angle varies with position?
  • How do planets rotate around their own axis?
  • What are seasons/solstices/equinoxes?
  • How day and night are formed? How do they vary in different seasons and locations?

Introduction

As stated in the previous tutorial, the Sun is the source of energy of our Solar system. All planets revolve around the Sun; it determines the structure and stability of the solar system due to its enormous mass (recall what we have discussed on gravitational force in Section 8). If the Sun did not exist, none of the solar system planets would exist either.

In this tutorial, we will provide some useful info about the Sun structure. Moreover, the planetary motion discussed in Section 8 (Kepler's Laws) will get a final answer on why it is so.
