Is it true that the sun when it is coming to the end of it's life will expand beyond the orbit of mars?

Answer 1

The sun will expand, but not out to the orbit of Mars. Most of the people who said yes in this question are wrong. It may expand to the current orbit of Earth (we can't know exactly how far). By this time though Earth's orbit will have expanded itself somewhat so our fair little planet will likely be saved from being obliterated, but the surface will have already been scoured and wiped out by this time anyway, so it's not as if there would be much left here to save.

Answer 2

A red giant that evolved from a one-solar-mass star like the sun does not get quite that big. At largest, it will get about as big as the orbit of the Earth. Since there is considerable mass loss prior to the red giant phase, the planets will have moved out to larger orbits, and only Mercury and maybe Venus will be actually engulphed by the red giant star.

During the red giant phase, the star becomes much more luminous, but also cooler (i.e. redder) at the surface. So the Earth will get overheated prior to the red giant phase. The sun will fill half the sky with a red glow like an electric stove on "high".

At the end of the red giant phase, the outer layers of the Sun will detach from the core, and move outward as a planetary nebula, passing by and engulphing all the planets. So eventually all the planets will be inside what formerly had been the outer layers of the Sun.

Answer 3

This has some skepticism to it. Most believe that the Sun will shallow up all of the inner planets. Others however believe that as the Sun expands, the orbits of all the planets will also enlarge themselves. But yes the sun will expand out the current orbit of Mars and possibly Jupiter when it nears the end of its life.

Answer 4

The answer is no. For several reasons.

1.) The sun is not alive, at least as far as we know. Attributing life to the sun is part of a phenomenon known as Animism.

2.) If you insist on the animist position however. When a star sheds it's outer layers into a planetary nebula, what remains behind is a white dwarf star. Technically, this would continue the "life" of the sun beyond it's red dwarf "death."

Answer 5

Scientists agree that it will expand beyond the orbits of Mercury and Venus. Earth is a bit tricky, some believe it may get near and that it will simply melt the outer crust of the planet but perhaps the inner core may remain in orbit.

Others believe it may go further and engulf the Earth. Time will tell...

Answer 6

It was the time at the creation of earth that the heavens consisted of a huge ball of gas matter which exploded and what the scientists called the big bang. Some of it blew out further into outer space and leaving only a portion to form our life giving sun. From the time of the dinosaurs,that ball of gas has never seemed to exhaust it's reserve of gas but burn and burn and burn. How does it manage to do this....it must be getting it's energy from somewhere. Scientists and astronomers looked into space and saw bodies of stars that once glowed but died out. They are comparing those stars to our sun and said that it will accumulate too much gas and burn more brightly then PHUT it will burn itself out and collapse and became a dead star. If that happens...we can kiss the world goodbye. There will never be a substitute for the sun.

Answer 7

Absolutely, but the sun has a lot of life left, we have worked out that this will be in a long time (5 billion years) so no immediate concern as in 3 billion the Milkey Way and Andromeda will collide and create a bigger explosion. But don't let this concern you or any of your friends as it is inevitable but very distant.

Answer 8

if the sun ever were to become a red giant as most main sequence stars do, yes it would expand a great deal. i dont know if would go quite to mars, but definitly through venus and mabey the earth

for the record, only supergiant stars have supernovas. hat will definitly not happen to our sun as it is only a main sequence star, it is an adverage star

Answer 9

The clue is you`re 14. You`re not on my own in the way you sense. very few youthful young ones escape with out have some unfavourable emotions approximately themselves. the only distinction is a few are very solid at masking up their emotions. a sparkling set of hormones are kicking in and it takes a at the same time as to get used to the ameliorations they make in the way you sense, and how you spot your self in society. You`re not suicidal, you decide on somebody to take heed to you and inform you that it`s ok, only about all those emotions will flow away. and that they are going to, it`s called starting to be an grownup. Many youthful young ones can get by this time on their very own. some have family individuals & pals to assist them. It`s confusing once you sense no-one helps you. however the help is obtainable and you`ve carried out the marvelous element in admitting you decide on some help. talk to your individuals, or to one particular chum, and tell them the way you sense. Have a solid coronary heart to coronary heart. do not overlook to take heed to them too, they`ll have themes too. It`s lots extra straightforward to speak approximately emotions & fears as quickly as one guy or woman admits there is an elephant interior the room

Answer 10

Yip, it'll certainly get warm round these parts then, fortunately, the sun's only half way through it's life and has a little way to go yet.
