Far more than that. In about 5 billion years the sun will exhaust the hydrogen fuel in its core. After that the fusion will move to the core and the sun will expand to become a red giant for about 2 billion years. After that the sun will fuse helium for about 100 million years before finally dying.

What will the world be like 50 years from now?
The continents will be very very far apart. Longer than 100 million years the continents might join together again like pangea. The earth will be very bumpy and jagged shaped in the time period of 50 million years from now. The continents will no longer be this close as they are. There will be much more erosion and mountains with glaciers. The earth will not be much pleasant with all the rough sights but the earth will always continue to move and one day the earth will be as it was more than imaginable million years from now.
In general how old are stars?
A typical star has an age of several billion years. Some stars have formed more recently, and are only a few million years old - or even a fraction of a million years, since new stars continue forming all the time. The oldest stars are just a bit younger than the "age" of the Universe (the time since the Big Bang) - which is currently estimated at 13.8 billion years.
What is the time taken by a to orbit the sun is a?
more than a million years
Can a protostar shine for more than 1 million years?
yes.
How much longer do scientists think the sun will exist for?
The sun is middle aged, it has burned for about 6 billion years and will burn for about 6 billion more years.
Should you worry about solar energy getting depleted?
Not really; the Sun will continue burning for several billions of years more. Before the fuel gets depleted, we will have another problem: in a few hundred million years, the Sun will grow too hot for life as we know it to exist on Earth.Not really; the Sun will continue burning for several billions of years more.

How long does a blue giant star burn?
How long a star takes to burn out depends on the mass of the star. It is estimated that stars can burn for billions of years. The understanding is the more mass a star has the faster it can burn out.
What time references best fits the concept of geologic time a dozen years a hundred years a thousand years a million or more years?
a million or more years
How old is the sun and when will it burn out?
the sun is 5 billion years old it will burn out in 5 billion more
Will the sun die in 2012?
Not a chance. The Sun will continue to "burn" for another 5 billion (yes billion) years. enough time to raise a family, enjoy grand children, great grand children and many more years. 5 billion years is 5,000,000,000 years. So now worries there.
Would geologic time be more like 12 years 100 years 1000 years or 1 million years?
Geologic time is very long, so a million or more years is the best choice.
How old is the Nile River?
As old as history itself, at least a few million years.
How long have dinosaurs been extinct?
Megalodon have been found dating back to 25 million years ago, and as recent as only 2 million years ago. That extends from the late Paleogene period through the Neogene and into the early Quaternary. They survived for 23 million years.
What best fits the concept of geologic time a dozen years a thousand years a hundred years or a million or more years?
Millions of million years, Billions of years, (Aeon).
How old was the Sun a million years ago?
The sun was roughly 4.6 billion years old a million years ago. The margin for error on the estimated age of the sun is more than a million years.
Is Coal a renewable or non-renewable energy resource?
Non-renewable because when we use it (burn it) it is gone forever. We can make more, but it takes about 300 million years, so we class it as non-renewable.
What has existed for at least 3 million years?
The universe has existed for more than 14 billion years, the sun for more than 4 billion years - both well over 3 million years.
