Type G stars are a category of stars that have a surface temperature between 5,300 and 6,000 degrees Celsius. They are often yellow in color and are known for their stable energy output, which allows for the formation of planets and the potential for life. The most well-known example of a Type G star is our own Sun. These stars typically have a lifespan of about 10 billion years and are found in various stages of their life cycle. Type G stars fuse hydrogen into helium in their cores, and as they age, they will eventually evolve into red giants before ending their life cycle as white dwarfs.
