How many Earths can fit into VY Canis Majoris, the largest known star?

Answer 1

Josiah Adams

About #7.5477xx10^10# earths can fit in VY Canis Majoris.

VY Canis Majoris has a diameter, which is roughly #2000# times that of our sun's and #155,000# times that of Earth.

Therefore, we can roughly

#pixx155000^2~=7.5477xx10^10# earths.

VY Canis Majoris is approximately 1,420 times the radius of the Sun. Earth's diameter is about 12,742 kilometers. Therefore, you could fit over 9.3 billion Earths inside VY Canis Majoris if they were placed side by side.
