Earth

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets (not counting the one dwarf planet Pluto) in the Solar System. The Guardians of the Universe themselves have said that Earth resides in Space Sector 2814.

History
Earth is a rocky planet orbiting the Sun, and the third planet in order from the star it orbits. The Detective Comics Collective Universe Earth has almost all of the same features of our reality: same countries, same personalities (politicians, movie stars, etc.), same historical events (World War II, 9/11, etc.), and so on with the exception that slight alterations may be present with these events.
