At a distance of 750 light years, we calculate Sadalmelik to have a luminosity 3000 times that of the Sun, rendering it about 60 times the solar diameter, large, but nowhere near as large as the truly great supergiants that would fill the orbit of Jupiter.

将其置于750光年的距离处，可算出它的亮度为太阳的3000倍，大小是太阳系的60倍，这个尺度使仅能够填充木星轨道的真正巨星望尘莫及。
