Type G refers to a classification of stars known as G-type main-sequence stars, or G dwarfs. These stars are characterized by their yellowish color and moderate temperatures, typically ranging from 5,300 to 6,000 Kelvin. The most well-known example of a Type G star is our own Sun, which provides the necessary light and heat to support life on Earth. G-type stars are important in the study of stellar evolution and the potential for habitable planets. They have a stable lifespan of about 10 billion years, allowing ample time for planetary systems to develop. Many exoplanets have been discovered orbiting G-type stars, making them prime targets for the search for extraterrestrial life.
