What are Giant and Supergiant Stars?
Giant and Supergiant stars are massive stars that have a much larger radius from other stars in the universe. To make a giant star, a regular star has to convert all the helium in it. When all the helium is converted it turns into a giant star. These stars are luminous stars, super bright.
