How big is a small medium star?

Answer 1

A small medium star, often referred to as a G-type main-sequence star, like our Sun, typically has a mass ranging from about 0.8 to 1.2 times that of the Sun. These stars usually have diameters between 0.9 to 1.5 times that of the Sun, translating to roughly 700,000 to 1.5 million kilometers. They primarily fuse hydrogen into helium in their cores and can have surface temperatures between 5,300 to 6,000 Kelvin.
