How many Earths can fit a bigger star?
Full answer: We need to know that the diameter of VY Canis Majoris is 155,000 times the diameter of the planet Earth. Suppose that numbers of Earths can be superimposed in VY Canis Majoris. Therefore, we can conclude that 7.5477 x 1010 Earths can be fitted to VY Canis Majoris.
