Possible for the sun to be pulled in by the earths gravitational field?..?

Question

What could cause this to happen, and if so what would happen to the earth?...

Answer 1

Errrmmmm............. Considering that the Sun is several thousand times the size of the Earth.....
I doubt that's gonna happen ☺

Answer 2

If the earth were not orbiting around the sun, the two would soon be pulled together.

When you've nothing better to do, you can work out the force between the sun and earth knowing their two masses and using the gravitational constant = 6.67300 × 10-11 m3 kg-1 s-2. The force must be the same as the centrifugal force of the earth orbiting the sun, given by ω²r, where ω is the angular velocity of the earth around the sun (you have to convert this into radians per second) and r is the average distance between earth and sum. So, you can find r.

I did the calculation once for earth and moon, and it's satisfying when you get the right answer!

Answer 3

At the moment this is not possible.

In order to overcome the Sun's gravity and pull the Sun, you would need a greater gravitational field than that of the Sun. Greater gravitational fields are found in denser stars like neutron stars and in black holes.

Hypothetically speaking, this would happen if the Earth became more massive and more dense; in fact, thousands of times more massive and more dense. Life would be impossible then, as we would get torn by the intense gravity. There are no known processes by which this can happen.

Answer 4

Theoretically speaking Earth pulls Sun and Sun pulls Earth. But the effect of Earth on Sun is negligible. So Earth can never pull Sun into its arms. However when all hydrogen on Sun burns up it turn a red giant. At that time the diameter of Sun would be more than the diameter of Earth's orbit around Sun. Hence before Sun gets to this size the Earth gets consumed by expanding Sun. If you would love to call this as Earth pulling Sun it cannot be dismissed.

Answer 5

Did you perhaps mean "Is it possible for the Earth to be pulled in by the sun's gravitational field?" Because that would be possible. Either way the Earth would melt, basically, and be completely vaporized. A good strong nudge by an asteroid or comet would get that process rolling.

Answer 6

Everything in space that has mass has gravity and applies this force to other objects. If a baby hits a football player with all their strength the football player will still be hit, but won't feel a thing. If the football player hits the baby we spoke of, well that baby will land some time right before the sun sets.
So the earth does affect the sun, but by such a small amount it is not noticeable. And in this case, it would be a baby, vs. maybe a blue wale. I think that would be about right.

Answer 7

The strength of any gravitational field is determined by the amount of mass producing it -- the more mass the greater the gravity. Okay, the sun's mass is 203,389 times greater than Earth's. You can figure out the answer from that.

Answer 8

well i will tell you one thing, scientists use the wobble effect of stars to see if their are planets around the star. Its the only way they are finding planets far far away. So if you can count a small small wobble effect, then yes the gravitational field does get pulled around a little bit, depends on the size of the planet. I'm sure the sun wobbles juuuuuusssstttt a littttttleeeeee. So your right!

Answer 9

* The earth does not pull the sun closer but it does along with the other planets pull away from the sun. Each planets does indeed get pulled into the sun however it takes so long that we will never see it in our life time or our children's children's life time etc..

Answer 10

The term "planet" or "moon" or "dwarf planet" are all arbitrary and thoroughly We Todd Did. Its merely language. there is not any genuine which ability to it. A moon is a planet, and a planet is a moon. they're the two merely hunks of rock hurtling by area. to call something a moon is to define it by ability of its relationship to a minimum of something else completely. A moon is a planet that orbits around yet another planet. A planet is a moon that orbits around a famous individual. between the Earth and the Moon, the midsection of gravity isn't the midsection of the Earth - we the Moon-Earth physique orbits the sunlight in an elliptical trend, yet neither does the Moon nor the Earth orbit the sunlight in an elliptical trend by ability of itself. the two the Earth and the Moon orbit around a single barycenter - the midsection of gravity, or of mass. Granted, the Moon strikes greater effective than the Earth does; is that on my own the defining function between a moon and a planet? How trivial. All bodies, to date as all of us be attentive to by ability of out present day know-how of physics, has a gravitational field that extends perpetually getting gradually weaker. there is, theoretically, no "outdoors" of our gravity. Presuming the Moon doesnt enter into orbit around the sunlight as its very own "planet", it is going to the two crash into something else, possibly the sunlight, or break out into deep area. Any alien passer-by ability of could in all risk call it a rogue planet.
