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 primarily composed of hydrogen and helium. The most well-known example of a G-type star is our own Sun, which provides the necessary light and heat for life on Earth. These stars generate energy through nuclear fusion, converting hydrogen into helium in their cores. G-type Main-Sequence Stars typically have a lifespan of about 10 billion years, spending the majority of that time 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.
