This cone—shaped nebula, 2,700 light years away from us and a neighbor of the festive Christmas Tree Cluster, stands an outrageous 15 light years high. If the Cone Nebula were the height of a 50—story skyscraper, our Solar System would be the size of a 10 cm drink coaster and our Sun would be the size of a silt particle, far too small to see with the naked eye.
