VY Canis Majoris

VY Canis Majoris in the Big Dog Team Star or VY CMa in short, one of the biggest stars known. This huge star, which is about 3.840 light years from Earth, is also one of the highest luminous stars.

Professor Roberta M. Humphreys of the University of Minnesota suggests that the radius of VY CMa is 1800-2100 solar radius. For a better understanding of the size, we can say that if we put VY Canis Majoris in place of the Sun, VY CM would occupy a space around Saturn's orbit. If we accept the upper limit of 2.100 sun radius, the light needs 8 hours to take a full turn at the surface of the star; This period is 14.5 seconds in the Sun. So we need about 650,000 hectares to take a tour around VY Canis Majoris. To fill it, 7 more than a dozen worlds are needed.

Considering that VY CMA is one of the largest known stars; when we realize that there are still unknown stars, we feel very small, do not we?
