In about 5 billion years, the Sun is expected to become a red giant.However, before that it will gradually get hotter, to the point that in 500 or 1000 million years, it may become to hot for any life to exist on planet Earth.
4-6 billion years
A+
About 5 billion years.
At least 5 billion more years. Ummmm The Earth isn't exactly 5 billion years yet. The Creation Science say the earth is only 6 thousand yrs old. f it was 5 billion the water would be so much salty in the sea.
The young star stage because at that stage, stars are just burning, no interruptions or disturbances
When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity, with that the core contracts and temperature rises. This cause outer layers to cool and expand. In this late stage of the star's life cycle, it is called a giant. The sun will continue to be a main sequence for about 5 billion years, then the sun will become a giant.
The star will move on to its next stage of evolution, along the Red Giant branch.
Protostar Stage
The sun is expect to remain stable for another three billion years.
