Still showing this to my Physics students every year, and have been
since 2016 when I found it. One of the best things I've ever come
across to help them understand the scale and emptiness and size of
our solar system. When they get this, then we start talking about our
solar system being just a small part of our galaxy, and our galaxy being
one of billions or trillions of galaxies, etc. etc. you see both the lightbulb
go off and the understanding set in. One of my favorite days in class
each year. Cheers.
