will a white dwarf hit our sun? or any other star?

Question

and when will it happen? will it happen? what will happen

Answer 1

A white dwarf is a small-to-medium star that has run out of hydrogen fuel and shed its outer layers. The core of the star collapses until mutual electron repulsion supports its weight. Then the star slowly cools into a brown dwarf. This is the fate of our Sun, but we've got about 5 billion years left before it becomes a white dwarf.

The chances of another star colliding with our own are extremely small. Even when two galaxies collide, the stars themselves rarely hit anything. The distances between them are too vast for many collisions to be probable. Gravity generally flings star systems around, sometimes ejecting them from the galaxy entirely. These events occur on a scale of millions or billions of years.

Answer 2

It's very unlikely in our local region of interstellar space over the next 6 or 7 billion years. Stars are very small compared to the average separation of three or four light years between them. Now there is one situation where it could happen, the core of a globular cluster or galaxy. There the stars are often mere light days apart, not light years. The central nucleus of a sprial galaxy could have 50 million stars or more crammed into a volume of space less than 50 light years across. Globular clusters are sparser, but the stars again are very close to each other and moving about in random directions. It is indeed possible for a white dwarf and a main-sequnce star to collide, which can result in a supernova when the white dwarf gets over the Chandresekahr limit and goes supernova, the two stars disrupt each other or they merge. Two small stars also can merge into a larger and hotter star in this way, forming "blue stragglers."

Answer 3

Extremely unlikely. Stars of any kind are very few and far between, and the odds of two of them colliding are virtually nil. If a star did come close to the Sun, we'd know about it for thousands of years, because stars move very slowly. It would be much more likely to enter a mutual orbit with the Sun than to collide.

Answer 4

A white dwarf star will not hit our sun anytime soon according to scietific research.

Answer 5

Collision between stars are extremely rare, except in the centers of globular star clusters, where they occasionally happen.

Answer 6

Probably not... Lol, not like we can't see a star coming...

Our sun IS a white dwarf.

Answer 7

u shouldn't worry about that, i don't think that's ever gonna happen in the near future, so....get a hobbie or something and relax...............

Answer 8

Off-the-wall question.

Where did you get such sillyassed info?

Too much time on your hands, daydreaming. And you want me to waste my time addressing this far-out "what-if"?

Answer 9

yes

Answer 10

no dont worry about that
