VY Canis Majoris

Our Sun, which accounts for most of the matter in our solar system, is about 870,000 miles across. You could fit about a million Earths in the Sun.

VY Canis Majoris, a star about 5,000 light years from us, is much larger than our Sun. VY Canis Majoris is so large that, if put where our Sun is, it would consume Mercury, Venus, Earth, Mars, Jupiter, and Saturn. It could be filled with 7,000,000,000 (7 Billion) Suns or 7,000,000,000,000,000 (7 Quadrillion) Earths.
