What is the moon?

Check out our closest neighbor—a world that's surprisingly complex when you look at the data. We're lookin' at a DISTANCE of 384,400 KILOMETERS on average; that gap is huge enough to fit every other planet in our solar system inside it! Because it lacks weather, the SURFACE is a permanent record of history, covered in CRATERS and fine, abrasive DUST that never blows away. If you were standin' there, you'd feel incredibly light because GRAVITY is only ONE-SIXTH of what we have on Earth—it's just not massive enough to pull on you any harder. As it orbits us, we see PHASES—that monthly cycle of changin' shapes caused by the angle of sunlight hittin' the lunar dirt. Finally, notice it has almost NO ATMOSPHERE. Without a gas shield, the moon can't trap heat or block radiation, makin' it a harsh, silent vacuum. Space is wild! Tiny Concepts.
