In that case, among other things:
Its pull on the earth would be 25% as strong.
One "Astronomical Unit" is (more or less) the average distance between the Sun and Earth.
The force of gravity between two objects is inversely proportional to square of the distance between their centers. For example: -- If the distance between two objects doubles, the gravitational force between them drops to 1/4 of what it was. That's 1/22 . -- If the distance between two objects gets multiplied by 5, the gravitational force between them drops to 1/25 of what it was. That's 1/52 . -- If the distance between two objects gets multiplied by 10, the gravitational force between them drops to 1/100 or 1% of what it was. That's 1/102 . Right now, the center of you is about 4,000 miles from the center of the Earth. If you doubled that ... went 4,000 miles straight up ... the gravitational force between you and the Earth would drop to 1/4 of what it is when you're here on the surface.
The minimum distance between the Earth and the Sun occurs during perihelion, which is when the Earth is closest to the Sun in its elliptical orbit. This usually happens around January 3rd of each year.
The distannce from Earth to Uranus is:19.2 miles x earths distancewhich is 1,747,200,000
If the distance between Earth and the Sun were doubled, the gravitational force between them would decrease by a factor of 4 (inverse square law). This means that the gravitational pull on Earth would be weaker, leading to changes in its orbit and potentially impacting its climate and seasons.
The strength of the gravitational force between the Moon and Earth would also double if the mass of the Moon doubled. This is because the force of gravity is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them.
Its pull on the earth would be 25% as strong.
If the distance between the Earth and the Moon is doubled, the gravitational force between them decreases by a factor of 4. This is because gravitational force is inversely proportional to the square of the distance. So, if the distance doubles, the force decreases by a factor of (1/2)^2 = 1/4.
If your mass was doubled, the force of gravity between you and the Earth would also double. This is because gravitational force is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between them. So, if one mass doubles, the gravitational force between them will also double.
One Fourth as muchNote:When you talk about gravitational forces, the "distance" you're working withis the distance between the object and the center of the Earth. That's about4,000 miles more than its altitude above the surface.
Tides would become stronger.
Tides would become stronger.
They would create a double greenhouse effect
Greater differences between summer and winter and more extreme weather.
If the distance between the sun and the earth changes, it can affect the strength of sunlight reaching the earth's surface. This change in distance can impact the earth's climate and temperatures. However, the earth's distance from the sun does vary slightly throughout the year due to its elliptical orbit, affecting seasons but not significantly impacting life on earth.
