Is the Sun Increasing or Decreasing in Size?
The Sun is a star and like all stars, it undergoes changes in its size over time. The Sun is currently in the main sequence phase of its life, which means that it is fusing hydrogen into helium in its core. This process releases energy that makes the Sun shine.
As the Sun fuses hydrogen into helium, its core becomes smaller and denser. This causes the Sun's overall size to decrease. However, the Sun's outer layers are expanding, which is causing its overall diameter to increase.
So, is the Sun increasing or decreasing in size? The answer is both. The Sun's core is decreasing in size, while its outer layers are increasing in size. Overall, the Sun's diameter is increasing.
The Sun's diameter is currently about 1.4 million kilometers. It is estimated that the Sun's diameter will increase by about 20% over the next billion years.
