What If Earth Was as Small as Pluto?

•

It's a small world after all, because today, we're shrinking Earth to the size of Pluto. But if our planet was this tiny, how would it alter the atmosphere? Why would the Earth get hotter? And how would gravity affect our water supply? Would we be tidally locked to the Moon? Would our planet still be habitable?

If Earth's Entire Population Lived in a Single Skyscraper
