VY Canis Majoris is the largest star known by human. It is located approximately 5000 million light years in the constellation Canis Major. As we know, light can traverse distance 300.000 km in one second. So, 5000 light years is 5000 x 60 x 60 x 24 x 365 = 157.680.000.000 km from our earth.
According to Dr. Roberta Humprey, VY Canis Majoris size is 2100 solar radii, or 2100 times of radius of our Sun. Look at these picture, to compare our Sun and VY Canis Majoris. If we walk 8 hour per day to circle our earth, then we need 2 years and 11 months to circle the earth. Comparing with 310 years and 7 months to circle our sun, and 650.000 years to circle VY Canis Majoris.
If we put VY Canis Majoris in the sun location, then the surface of this star will extend the Saturn orbit. Hmmm, very amazing… God Almighty….
