Explanation:

1} the Big Bang model is the most accepted theory about the birth of the universe.

2}  A star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity. The Sun is the closest star to Earth.

3} Sun is the celestial body that  lies at the center of our solar system.

4} The gravity of the earth is what is holding you onto the surface and what pulls you down when you fall but the gravity of your body also pulls the earth toward you, to a point. As the earth orbits the sun, the sun also is pulled a little bit towards the earth because of earth`s gravity.

5} Lunar Cycle is the waxing period of the Moon.
