A yellow star is a G-type main-sequence star; our Sun is one of these. Yellow stars have a solar mass of 0.81.2 M ☉ and a surface temperature of approximately 5,0006,000 K. In the image below you can see all the stellar types and their colors, and minimum and maximum radii.
Based on the false belief the sun is a gaseous object. It's not it's a solid object making it's mass tremendously larger.
