This is how the moon would look in the sky if it were a disco ball

Vsauce's Michael Stevens answers a great question with the help of Yeti Dynamics: What if the moon was a disco ball?

When the Moon first formed, its rotational speed and orbit were very different than they are now. Over time, the Earth's gravitational field… » 2/24/14 8:15am 2/24/14 8:15am

China's Lunar Rover Only Lasted a Month
