How Do Glaciers Move?

This video is so cool, it's ICE COLD Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub ↓↓↓ More info and sources below ↓↓↓ Glacier ice is weird. It’s solid. Solid things aren’t supposed to flow. But glacier ice flows like a liquid, and it does that without melting! How is this possible? I traveled to Mendenhall Glacier in Juneau, Alaska to find out.

While our moon does cancel out some tugging from the other planets in the solar system, here's a recent paper shows that moonless planets can orbit with great stability even without the influence of a moon.
