In the stellar classification system, a star that is rated G V is a dwarf star (see also Main Sequence) that is white or yellow-white in color. These bright stars convert hydrogen into helium by nuclear fusion in their core. They are brighter than 90% of the stars in the cosmos, and have a surface temperature between 5,300 and 6,000 K.
Whether you knew it or not, you're already quite familiar with what it's like to live under a G V star - our Sun is pretty typical for the class. Our sun, as with all young G Vs, is actually white. It only seems yellow through our atmosphere via an effect known as Rayleigh scattering. None the less, our class of stars is often known as Yellow Dwarf stars.
G V Stars have a projected lifespan of around 10 billion years. After that, they expand to many times their original size and become a Red Giant.
Game and Story Use
- Life evolved in our solar system under the auspices of a G V Star - so similar life could evolve on planets in other systems with similar stars.
