In Response To: 1 in 4 Americans Don’t Know Earth Orbits the Sun. Yes, Really (Susoni)

I am pretty sure Bill Nye is not a scientist. He is an actor that plays a scientist. I thought I would provide a video on how our solar system really works. The author of the video states, This is a non-conventional view of our solar system that is different from the standard ‘flat’ diagrams. I believe this video represents the way our solar system works…
Notes on this video
The Milky Way
– The Milky Way itself travels through space at appr. 600 km/s
– The image used for texturing the Milky Way is NOT a picture of the Milky Way. There are no pictures of the outside of the Milky Way.
– There could either be a black hole or a central sun in the center of the Milky Way. I went with the texture image and made it shine.
– A complete revolution around the galaxy takes 226 million years
– Do not confuse the Galactic Plane with the Galactic Equator: the Sun never “crosses” the Galactic Equator because the Sun is always on the Galactic Equator, by definition.
– One precession cycle takes 25,920 years
– Since one revolution takes 226 mln years, this would mean that there are appr. 8692 precessional cycles in one revolution. In this animation there are only 60.
