SOLAR SYSTEM

Detailed explanation-1: -Earth. Moon. If Earth had twice the mass it has now, how would the gravitational force between it and the Sun change? The gravitational force would be twice as much as it is now.

Detailed explanation-2: -Essentially, an increase in mass means an increase in gravity, while a decrease in mass means a decrease in gravity. So if the Sun spontaneously lost half its mass (gasp, shudder, the horror!) then its gravitational pull on Earth would lessen as well, ultimately changing the very nature of our orbit around the Sun.

Detailed explanation-3: -The force exerted on the Earth by the Sun is equal and opposite to the force exerted on the Sun by the Earth. If the mass of the Earth were doubled, the force on the Earth would double. If the mass of the Sun were doubled, the force on the Earth would double.

Detailed explanation-4: -As one mass increases, the gravitational force between the two bodies increases proportionally. Therefore, if Earth’s mass were doubled, the gravitational force between the sun and Earth would double as well.

Detailed explanation-5: -Life would be: Built and proportioned differently. If gravity were twice as strong, bodies possessing the same construction and mass as our flora and fauna would weigh twice as much and would collapse.

Detailed explanation-6: -Because of the gravitational force between the Sun and the Earth, the earth orbit around the Sun. If suddenly the Sun vanishes, the gravitational force between the Sun and the Earth will disappear. So, the Earth will no more be able to orbit around the sun.

Detailed explanation-7: -6. If Earth’s mass doubled without changing its size, what would happen to your weight? Your weight would double because gravity would double.
