Our Sun is about 2000 times smaller than the largest star discovered by humans.
If the Earth were to be represented by a sphere one centimeter in diameter, the Sun would be represented as a sphere with a diameter of 109 centimeters, at a distance of 117 meters. At these scales, VY Canis Majoris would have a diameter of approximately 2.3 kilometers.
Canis Majoris (means Big Dog in Latin) is a dying star, it is located in our Milky Way Galaxy and is only 5000 light years away from the Earth!
