What is the biggest globe in the Universe ?

"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 one hundred and nine centimeters, at a distance of one hundred and seventeen meters. At these scales, VY Canis Majoris would have a diameter of approximately 2.25 kilometers." Source
