The sun is expanding . Will it attract the earth & other planets into it or all of them will vapourise?

Question

According to the scientists the sun is a active star and its volume is expanding. So gravity also increasing so that eventually all the planets of our solar system will plunge inside the sun or may be all of them will vapourize because of tremendous heat?

Answer 1

Gravity doesn't increase with volume, it increases with mass. As the sun burns off it's lighter fuel and starts fusing heavier elements it will start getting bigger, however because it's radiating so much energy it's mass is actually decreasing. The sun will get bigger and eventually engulf the earth's orbit but the earth will move out into a cooler orbit.

Answer 2

No. The Sun is not expanding yet.
In about 5 billion years it will reach its red giant stage however and will start to expand rapidly then but its mass will not have changed significantly so gravity alone will not pull the planets towards the Sun.

What will is a combination of drag and gravity. Drag from the Sun's atmosphere will cause the planets to slow down and orbit ever closer just like a returning spacecraft enters the Earth's atmosphere to slow down.

They will continue spiralling in towards the centre of the Sun actually orbiting within the Sun's outer atmosphere until they are vapourised.

Answer 3

There is nothing we can to save are home planet earth but every million years the sun gets hotter with burning all is hydrogen by 1'C one day the space in witch life is possible will move out and the next planet we could think about calling home is mars there will be some people witch will be able to say there good by to planet earth as the sun takes make what it gave “life” yes the ion in are blood is star dust in fact we came from starts as the core of a star has a solid mass of ion. And when a star blows up it realises these building blocks of life!

Answer 4

Gravity is a function of mass. The fact that the sun may be expanding (if it is) would not affect its mass and would therefore not affect its gravitational pull on the Earth.

In abut 5 billion years the sun will start expand into a red Giant.

At that time its size may increase to exceed the orbit of the Earth and the Earth will be destroyed.

Answer 5

Our water and atmosphere will vaporize, the mass of the sun will not increase significantly so gravitational attraction to the sun will not increase, however the electromagnetic activity of the sun will likely increase drawing the earth closer to the sun.. Furthermore the sun's radiation pressure will increase, perhaps pushing the earth outward and away from the sun . I think this radiation pressure would be counteracted by the increased electromagnetic force though.

Answer 6

The earth's orbit is a perpendicular action to the gravitational tension of the sunlight. If the earth slowed, it would fall in direction of the sunlight, if it slowed adequate, it would fall into the sunlight. If it speeded up, it would get extra distant from the sunlight. If it speeded up adequate, it would have the escape velocity to flee the image voltaic device. easily, the two a variety of issues take place... properly, no longer the falling into the sunlight and the escaping orbit, however the earth's orbit is elliptical. Kepler's 2d regulation tells us some thing concerning the fee of a planet and that's proximity to the sunlight. It is going swifter whilst it quite is closer, and slower whilst it quite is farther. So, whilst the earth is farther faraway from the sunlight, it quite is orbiting extra slowly, this slower circulate consequences interior the earth shifting fairly closer to the sunlight. yet because it gets closer, it advantageous factors momentum... which, in turn, makes it start to inch away. Perihelion (closest attitude to the sunlight) for earth oftentimes happens on or around January 2, whilst aphelion (farthest distance from sunlight) is approximately around July 4. So, you would be chuffed to renowned that, interior the northern hemisphere, wintry climate is going by employing fairly swifter, by way of fact we are close to perihelion and our planet "sweeps equivalent section in equivalent time" as consistent with Kepler's 2d regulation. interesting i know. humorous the way you used the be conscious equilibrium, it is basically what an orbit-device establishes, as long by way of fact the orbit is robust.

Answer 7

first, the earth would be engulfed in flames as the sun puffs up from the lack of hydrogen. only then, would it create a nova, not a supernova, and shrink into a neutron star. the earth would eventually cool down from it's millions of degree temperature down to hundreds of degrees below zero. so basically, the hearth could hypothetically split in half from the sudden temperature change. the reason for this theory? on the History channel there was a program called "Modern Marvels" about dynamite. it said that in midevil times fires were set near rock that was going to be broken and then when it was glowing red hot, cold water was put on and the temperature change caused it to crack. this would not happen for millions of years though as scientists believe, in fact I think it is a strong cause of global warming.

by the way djdr, the sun is too small to cause a supernova. it will puff up into a red giant and then create a much smaller but still massive nova. this will turn it into a neutron star or white dwarf, which i did not mention before.

Answer 8

actually what will happen is the sun will die in about 20 billion years or so, there will be a supernova, followed by a black hole, at which time everything will be sucked into the black hole. Then in a bout another 50 billion years or so there will be enough matter fo form a nebula, in which a new star will be born and the whole process will start all over again. And in about 100 billion years we will be having this very same conversation all over again

Answer 9

yes offcourse.
addition to this i want to give information that i received from
space reseach center.
"UNSPOT BREAKUP: Big sunspot 898 is breaking apart, sending shock waves
through the sun's atmosphere and radio bursts toward Earth. You can
listen to some of the radio sounds at http://spaceweather.com . The
breakup does not herald a major solar storm, but it does offer an
opportunity to watch a sunspot in its death throes--very entertaining.

STORMS ON JUPITER: The long-awaited glancing collision between
Jupiter's Great Red Spot and Red Jr. is underway. So far the two massive
storms are holding their own, resisting disruption. Closest approach is
still a week away, however, and astronomers will be monitoring the
situation closely. See the latest images at http://spaceweather.com .

Answer 10

No, even though the suns size is increasing, its gravitational field strength does not increase. An objects gravitational field depends not only on its size but also its mass, in short it depends on its density. Though the sun increases in size, it decreases in density. Most likely the sun will expand to a size which envelops the planets and destroys them.
Hope i helped
