If the sun instantaneously became a neutron star,say,the size of Texas,what would happen to the earth???...t?

Answer 1

If you were to snap your fingers and change the sun into a neutron star of equal mass, the gravity wouldn't change, but the lack of energy output would render the Earth completely unhospitable for life. Simple organisims like microbes might find a way to survive, but all complex forms of life would perish without the Sun's light and warmth.

Answer 2

If the sun instantaneously became a neutron star the size of Texas, the neutrons wouldn't be able to resist the force of gravity, most neutron stars are about 10 km in size, and instantaneously become a black hole, but either way the Earth would be "sucked" directly into the neutron star or black hole. Sucked is a bad word to use but thats pretty much what will happen (a paper clip with the density of neutron star material would weigh more than Mt. Everest). So a neutron star or black hole the size of texas would have so much more mass than our sun, Earth would be "sucked" into it.

Answer 3

Nothing at all, if you mean that the Sun is compressed to that size without adding or removing any matter. Gravity at our location, 93,000,000 miles from the Sun, would not change. Now if the change to neutron star also changed the energy output of the Sun, so that it was hotter or cooler, or emitted more dangerous radiation, that would be a problem. But as far as gravity is concerned, there would be no effect at all. Even if the Sun became a black hole, it would be the same, gravity at Earth's location would not change and Earth would go on orbiting just like it always has.

Answer 4

you are like 3 steps ahead already. 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. I hope that helped.

Answer 5

A neutron favourite individual is a 2 to three image voltaic mass body about 12 km in diameter. The sunlight will amplify to a purple tremendous then finally contract and change right into a chilly cinder if the universe lasts that lengthy.

Answer 6

The earth would be drawn out of its orbit, more towards the sun, because of the increased gravity. Often neutron stars have high intensity radio beams coming from their equatorial lines thus we most likely would be blasted by these high intensity radio waves causing tremendous CHAOS.

Answer 7

The earth would get cold, We'd prob be dead in about a month from lack of heat and food. Gravity would change, but it wouldn't disappear. I believe gravity would lessen somewhat, so we would get thrown on a more elliptical orbit.

Answer 8

first, the sun will never be a neutron star.

second, neutron stars are about ten kilo-meters across.

sorry

Answer 9

the earth would freeze and problay go into space forever until it hits sum thing

Answer 10

the earth would freeze then it would colled with another plantet. no more gravityall life on earth would die
