Human figure is for comparison. In reality humans and dinosaurs didn't live at the same time. 1km Diameter of Barringer Crater in the northern Arizona desert (1186m). 100km Jamaica Island (235km long). 10000km Diameter of planet Earth (12,742 km). 10^8m Moon's orbit (770,000km). 10^9m Diameter of the Sun (1391400km). 10^11m Diameter of the inner Solar System. (600,000,000 km) 10^13m Diameter of the Solar System. 10^15m Outer limit of the Oort Cloud. 10^16m Distance to Alpha Centauri. 10^18m Messier 13 globular cluster. 10^20m Diameter of the Milky Way Galaxy. 10^22m Local Group of galaxies including Milky Way, M31(Andromeda), M33, SMC, LMC and smaller galaxies. 10^23m Typical galaxy cluster (2 to 10 Mpc). 10^24m Laniakea Supercluster of galaxies. (160 Mpc) 10^25m End of Greatness ("Cosmic web" structure). 10^26m Diameter of the observable universe sphere. The entire Universe is larger than 10^27m and possibly infinite.
