The video “Star Size Comparison” (duration: 2:34) nicely visualizes how tiny Earth (diameter 12756 km) is compared to the Sun (diameter 1,392,000 km, 109.1 times Earth’s). And how tiny the Sun is compared to other stars. Factoid from the video:
VY Canis Majoris (a red hypergiant) is the largest known star. It has a diameter of 2,800,000,000 km. It would take an airplane 1100 years to circle it, if it was flying at 900 km/h.
