Gravity is a universal force that binds together planets within solar systems, and keeps our feet on the ground walking around planet Earth. The sun is very important to life on Earth, as it not only provides us with warmth and light, but affects our gravity.
The sun is a very large star, and is the largest celestial object in our solar system. The sun is 1,390,000 kilometers in diameter, so it’s size creates a very large magnetic pull. Thanks to the sun’s huge magnetic pull, it creates gravitation, pulling all the other planets in line with it. The very reason that Earth and the other planets in our solar system experience a regular orbit, is because the sun influences these bodies with it’s huge gravitational force.
In order to find the gravitational pull of the sun, you take the gravitational constant of 6.67 times 10 to the negative 11th power, and multiply it by the mass, and divide that amount by the radius squared. The sun has a mass of 1.99 x 10 kilograms to the 30th power, and a radius of 696,000 kilometers. The gravitational pull of the sun is calculated by following this formula. Try it now!
