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 Sun is a prime example of a G-type star. These stars generate energy through the process of nuclear fusion, converting hydrogen into helium in their cores. G-type stars have a lifespan of about 10 billion years, with a stable phase lasting around 10 billion years before evolving into red giants. Their stability makes them ideal for hosting planetary systems.
