Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Why do the planets orbit the sun?
A
They don’t, the planets orbit the Earth
B
Because Science
C
The sun is so massive that it has a very large gravitational pull, which causes objects to orbit it
D
Because they want to
Explanation: 

Detailed explanation-1: -The Sun’s gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. Even spacecraft are in motion through the solar system, either in orbit around the Earth or Moon, or traveling to further worlds, because of gravitational forces.

Detailed explanation-2: -Anything that has mass also has gravity. Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is.

Detailed explanation-3: -In 1915, Albert Einstein figured out the answer when he published his theory of general relativity. The reason gravity pulls you toward the ground is that all objects with mass, like our Earth, actually bend and curve the fabric of the universe, called spacetime. That curvature is what you feel as gravity.

Detailed explanation-4: -The answer lies in the same fact that keeps Earth from plunging into the Sun: Our planet is traveling very fast-about 67, 000 miles per hour-almost entirely sideways relative to the Sun.
