It’s a game so I couldn’t get the sizes right cause it was a game.And the reason why I made Sirius A a Red Giant is because there are 4 different stars.Yellow Star,Red giant,Blue Giant, and White Dwarf.Blue Giant is the largest and White Dwarf Is the smallest. Red giant is in between in sizes of Yellow Star and Blue Giant. Red giant is the second largest.So I had to make it red.
