What will happen if the sun is hollow inside?

Question

What will its effects on:

1. Earth's orbit
2. Earth's climate
3. Other planets' orbit
4. Earth's rotation

Please!!!Help me!!!

Answer 1

If the sun were hollow then a significant portion of its mass would be gone.

Without mass, a significant portion of its gravity would be gone.

Depending how much mass (and gravity) were missing, the sun's gravitational influence on the planets would lessen. The kinetic energy of the planets rotating around the sun would cause them to move to more distant orbits. The outer planets may escape the gravitational well of the sun entirely, and escape into deep space. Depending on how "hollow" the sun becomes, the Earth would either migrate outward or escape the sun's orbit entirely. Either way, the oceans would freeze, the climate would plummet and the Earth would be sterilized.

However, because the Earth's rotation is not connected to the sun's gravity (or anything else - it's a result of the accretion process) the Earth's rotation would not be affected.

Of course, if the sun suddenly became hollow it would collapse on itself and probably explode, taking the Earth with it 8 minutes later.

Answer 2

well it can't be hollow, but to guess the "if", I'm not an expert on impossible to answer questions.

I'm going to assume that other than less mass this hollow sun is to be exactily as it is now.

1. The earth would have to be a bit closer to the sun, that would make years shorter and depending on how close a bit hotter.

2. If the earth was still cool enough to have liquid water on it, the climate would probably be about like it is in the mid east. So life would be hard.

3. if it was hollow it would have less mass, less mass would make less gravity, less gravity pulling on the planets would mean that the planets would have had to have formed closer together, if that happened what would have been the earth may have crashed into Jupiter, I'm sure Mars would have. The outer planets would be floating out into space or never formed in the first place.

4. I'm not sure about this, but I think the moon has more to do with the earths rotation than the sun does.

Answer 3

Astrophysics has built up a lot of math and theory to explain cosmic phenomena as we understand it. A hollow Sun would cause a tremendous problem for it. So you'd have to determine whether you meant the Sun suddenly became hollow, or you meant that the Sun is hollow and we just misunderstood all this time.

If the Sun suddenly became hollow (exactly how hollow?) Its mass would be substantially reduced, and therefore its gravitational field. Its fusion reaction would likely fail so it would start collapsing. Aside from the consequences of that disruption, Earth and the other planets would drift into much wider orbits, and become much colder, both from distance and the missing solar radiation. Earth's rotation probably would not change as a direct consequence.

If we simply didn't realize that the Sun is hollow, probably nothing would change, but it would nean that we don't really understand stellar mechanics and would have to doubt every prediction we made until we could reconstruct a compatible model.

Answer 4

Does it retain the same mass and diameter? If so, nothing will happen.
If the sun retained the same density of plasma, but was hollow, and for some reason stable in this condition, and retained the same diameter, then it would necessarily be less massive. In that case, if the diameter of the earth's orbit were to stay the same, its radial velocity would have to be reduced. The earth's rotation would not be affected in any measurable way for billions of years, if ever, so minute is the influence of tidal forces from the sun. Other planets would have the same changes to their orbit as the earth did. The earth's climate would be affected by the temperature of the sun. it is hard to say what effect hollowness would have on temperature, since hollowness isn't really possible. You haven't supplied sufficient information to answer this question properly.

Answer 5

1. If the sun was hollow, well assuming it was the same size the mass would drop like the stock markets and we would (most likely) have an effect on the sun's rotation.
2.Most of the sun's heat comes from the inside, so we would be a floating chunk of ice.
3. The gas giant planets would literally make the sun rotate around them.
4.Heck the loss of something to orbit around would fling the Earth randomly with the sun in tow, although if Jupiter went another direction it would the Earth and sun that way.


Let's hope this doesn't happen!


And what do you mean by "What will it's effects be on:"?!
Can you predict the future?!Let us in on it!

Answer 6

As in, the mass disappears?

In that event the planets would drift into interstellar space almost tangential to their current orbits. That would, of course, impact climate as the sun fades into the interstellar background. Earth's rotation would not be affected.

However, nuclear fusion occurs within the sun's core, due to its mass and heat. If the solar interior were replaced by vacuum, no more fusion--no more light and heat. The sun would wink out fairly quickly, accelerating earth's environmental impact.

If the sun were hollow but the mass were evenly redistributed around its shell (conservation of mass), again we should expect fusion to cease and the sun's energy output to fall next to zero. In this scenario, all the planets orbits remain unchanged, and their spins, but again they rapidly cool.

What is the temperature in midafternoon? What is it in the morning, just before sun rise? Imagine that difference, day after day, levelling off only as earth's surface temperature approached absolute zero. The oceans hold heat, and their is heat in earth's mantle from the slow decay of fissionables there and in the core. So the earth would not reach absolute zero, but it would get really cold and dark. No moonlight. Only starlight. The clouds should also disappear, so the stars would be really bright, 24 hours a night.

Answer 7

that's an thrilling question, and that i'll respond to in view which you're saying you're honestly involved. the respond, in accordance to classical optics, is that the sunshine bouncing around interior the sphere would boost until the quantity of sunshine misplaced by using the sphere (the two by using absorption or transmission) equals the quantity getting into by using transmission. by using ways, the transmission by using a "one-way mirror" is identically the comparable for the two guidelines, so in case you will get mild in, mild of the comparable wavelength can come out. that's barely reflection and absorption which will properly be distinctive from the two aspects. you could ask, even with the undeniable fact that, what would ensue in case you incorporate a fluorescent fabric interior the sphere which converts the incoming mild to an prolonged wavelength (distinctive shade) which the mirror would not transmit. if so, the tip result relies upon on which beginning assumption fails first.

Answer 8

Nothing for 1,3 an 4 but the climate would go down the tubes. Without a core and all the pressure on it from the gravitation force on all the gas in the sun, nuclear reactions could never happen. The Sun would be cold.

Answer 9

It's a BS question... it *can't* be hollow, it's like wondering what would happen if 2+2=5

Answer 10

The sun is not hollow, homeboy. I don't know where you are going with this.

You may as well as what would happen if my dog was a cat.
