      There are many times more stars in our universe than there are grains of sand on every beach on Earth, so it is really hard to be exactly sure of the largest star. However, one of the largest stars we know of is Canis Majoris.

      If you were travelling at the speed of light it would take you almost 4000 years to reach it and the star itself is 1500 times larger than our own sun. A passenger jet would take 1100 years to fly around it just once!
