Which property of the Sun most affects the strength of gravity?
Size: The Sun has much more mass than any of the other objects in the Solar System. In fact, about one million Earths could fit inside the Sun! Its great mass gives the Sun very strong gravity. Earth and the other objects in the Solar System follow continuous orbits around the Sun because its gravity is so great.
What gives the Sun its strong gravitational force?
The Sun is a lot more massive than the Earth, and so it has a stronger gravitational field. The Sun exerts the same gravitational force on the planets as it would if it had the same mass but was made of rock.
How does the Sun affect gravitational force?
The Sun’s gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. The closer the planet is to the Sun, the greater the pull of the Sun’s gravity, and the faster the planet orbits. This model fails in that objects in stable orbits do not fall into the Sun.
What factors affect gravitational field strength?
The force of gravity depends directly upon the masses of the two objects, and inversely on the square of the distance between them. This means that the force of gravity increases with mass, but decreases with increasing distance between objects.
What determines the strength of gravity?
The magnitude of this force depends upon the mass of each object and the distance between the centers of the two objects. Mathematically, we say the force of gravity depends directly upon the masses of the objects and inversely upon the distance between the objects squared.
Which of these factors affect gravity?
Factors That Influence the Strength of Gravity Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them.
Which is greater Earth’s gravitational force on the sun or the sun’s gravitational force on Earth?
The earth’s gravitational force on the sun is equal to the sun’s gravitational force on the earth.
Does the sun or Earth exert a greater gravitational force?
Our sun is 27 million times larger than our moon. Based on its mass, the sun’s gravitational attraction to the Earth is more than 177 times greater than that of the moon to the Earth.
How does the Sun’s gravitational pull effect the Earth?
The sun’s gravity pulls the planet toward the sun, which changes the straight line of direction into a curve. This keeps the planet moving in an orbit around the sun. Because of the sun’s gravitational pull, all the planets in our solar system orbit around it.

What variables have the most effect on the strength of the gravitational attraction between two massive objects?
Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them.
