G-Type Main Sequence Stars, often referred to as G dwarfs, are a category of stars that have a surface temperature between 5,300 and 6,000 Kelvin. They are characterized by their yellowish color and are typically found in the middle of the Hertzsprung-Russell diagram. Our own Sun is a prime example of a G-type star, which plays a crucial role in supporting life on Earth. These stars fuse hydrogen into helium in their cores through nuclear fusion, a process that generates energy and light. G-type stars have a lifespan of about 10 billion years, spending the majority of their lives in a stable phase known as the main sequence. After exhausting their hydrogen fuel, they will eventually evolve into red giants before ending their life cycle as white dwarfs.
