In heaven,God uses star mass unit(smu) to measure weight of galaxies . 1 smu = 1/30th of the mass of the star.If the mass of our milky way galaxy is 900 smu, mass of how many stars will be equal to the mass of milky way galaxy?
The distance (in km), from one edge to the other edge of the Milky Way is:
The Astronomical Unit (AU) is a unit of measurement based on the average distance between what two bodies?
