1. If the sun was twice its size: Increasing the size of the Sun would actually increase the gravitational force between the Sun and Earth. According to Newton's Law of Universal Gravitation, the gravitational force is directly proportional to the mass of the objects. Therefore, doubling the size (mass) of the Sun would increase the gravitational pull on Earth.
2. If the Earth was twice its size: Increasing the size of the Earth would also increase its mass. As mentioned above, the gravitational force is directly proportional to the mass of the objects. Thus, doubling the size (mass) of the Earth would increase the gravitational pull between the Sun and Earth.
3. If the Earth was closer to the sun: Decreasing the distance between two objects will increase the gravitational force between them. Therefore, if the Earth were closer to the Sun, the gravitational pull between them would increase.
4. If the sun was farther away from the Earth: Increasing the distance between two objects decreases the gravitational force between them. Thus, if the Sun were farther away from the Earth, the gravitational pull between them would decrease.
What would decrease the gravitational pull between the Sun and Earth if the sun was twice its size, if the Earth was twice its size, if the Earth was closer to the sun, if the sun was farther away from the Earth
