00:00The Milky Way is so large that light itself needs over 100,000 years to cross it.
00:07Inside this galaxy are hundreds of billions of stars.
00:11One of them is our Sun, and around that Sun, a tiny planet called Earth.
00:18Now here's the disturbing part.
00:20Our entire solar system is drifting through the galaxy at over 800,000 kilometers per hour.
00:27Yet it still takes hundreds of millions of years to complete a single orbit.
00:32That is the true scale of the Milky Way.
