G-Type Stars are a category of stars that have a surface temperature between 5,300 and 6,000 degrees Celsius. They are characterized by their yellowish color and are often referred to as yellow dwarfs. 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 typically have a lifespan of about 10 billion years and undergo nuclear fusion, converting hydrogen into helium in their cores. G-Type stars are common in the universe and can host planetary systems, making them important for the search for extraterrestrial life.
