Here are the notes from the discription:
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.
Scale & distance
– the Sun is 109 times bigger than the Earth. If this animation was to scale, the planets would be invisible.
– Our Solar System should be a gazillion times smaller compared to the Milky Way. If this animation was to scale, you could not see the Solar System, the Sun or any of the planets.
– The software used to create this animation is unable to work with extreme sizes and distances.
