Just click the green flag and watch A short animation to show you how small our world is All proportion are correct! (Except the distance between moon and earth. That would be too far away) FCM (Frequently commented mistakes) Yes. Canis majoris is probably not the biggest star known. It is UY Scuti. The size comparison between Earth and UY Scuti is comparing the radii and not the Volume. Latest Researchs (2017) show that Canis Majoris is probably the second biggest star known. Thanks to @Colorgram for the update No the big red spot is currently not that much bigger than Earth because it shrunk signifficantly.
