is the sun getting weaker and weaker?

Question

is the sun gradually burning itself out?

Answer 1

The sun is getting gradually hotter and hotter. As hydrogen turns into helium in the Sun's core, the core gets a little denser and hotter. This is a very long-term effect, however.

There are short-term (for the Sun, at least) fluctuations in the Sun's energy output. There is some evidence that such a fluctuation could be partially responsible for our current spate of global warming, although human activity likely also plays a role (so we're not entirely off the hook). Satellites orbiting Mars have also detected this increased solar output, so it's not just an "Earth problem."

Hope that helps!

Answer 2

it will burn out itself after 5 billion years thats when it turns to be a super nova and i'm having a feeling if thats how the world will end.Because if the sun is gonna turn into a super nova there won't be enough energy for anything. the earth is at a specific distance from the sun thats why life exists on the earth. if no sun no energy and no energy no life.

Answer 3

Nope. Over the next few billion years, as it uses up its supply of hydrogen, it will actually get a little hotter (note - this is not the current source of global warming). In about 4 or 5 billion years, it will exhaust the hydrogen in its core, and will begin to expand as it becomes a Red Giant star - at which point, Earth is toast.

Answer 4

Actually it is getting larger and hotter, but its not enough to change the temperature of earth or significant enough. In due time about 4 to 5 billion years from now it will blow up. It will become a black hole sucking everything in sight or become a dwarf star and burn a few more billion years.

Answer 5

it is middle aged and has an extremely long life ahead, although at some point in the eztremely distant future the sun will have expanded to be like a red giant and it will encompass the space that included Earth all the way out past Mars, how about that

Answer 6

Actually, right now the sun is generating more energy that it did a few decades ago. That is one of a number of reasons that there is global warming.

Eventually, billions of years in the future, it will explode. Personally, I'm not too worried that it will concern me at that time.

Answer 7

Yes it is But it's going to be about 5 billion year in the future. And when it explodes it is gonna blow up the first 3 or four planets!

Answer 8

unless you are really long lived you wont be around to see it grow out and the earth become a really cold place to live. But it will be like 10 milliln years

Answer 9

yes of course.

the fuel of the sun is not unlimited, it gradually decreases over time. but we dont have to worry, it wont happen in our generation. maybe billions of years after.

Answer 10

Although its burning itself out it is not becoming weaker, its actually becoming more intensified.
