If you haven’t seen this 7 minute movie on the scale of the universe (which was just released on September 16th) then you need to. It’s amazing. My only quibble is that they placed the edge of the Solar System at Neptune’s orbit (3.5 miles by scale from the Sun) rather than at the heliopause (which would be closer to fourteen miles by scale). But like I said, that’s a quibble. Sit back and get a sense of the scale of our cosmic backyard.
