Question

the sun. like 80 to 90 percent of stars, is in which stage of life

Answer 1

The Sun is currently in the main sequence stage of its life cycle. This stage is characterized by the fusion of hydrogen into helium in the star's core, which produces energy that supports the star against gravitational collapse. The main sequence phase is the longest stage in a star's life, and for a star like the Sun, it will last for about 10 billion years in total. The Sun is approximately 4.6 billion years old, meaning it has about 5 to 6 billion years remaining in this phase before it evolves into the next stages of its life cycle.
