Red giant is a stage in the life cycle of a star, characterized by a significant increase in size and luminosity. It occurs when a star like our Sun exhausts the hydrogen fuel in its core, causing it to expand and cool.
This process begins when a star's core hydrogen is depleted, typically after about 10 billion years. Without
