Here’s a neat little video, which holds the Milky Way (galactic-centric) steady as the Earth rotates relative to it.

For comparison, here’s the original video by Stephane Guisard and Jose Francisco Salgado, showing the geocentric view of the sky moving:

It is always revelatory to see things from unexpected perspectives. Brian Swimme was amazed by the immensity of it when he first truly recognized that he was standing on a planet that was rotating through space orbiting the Sun.

The inner planets. (from my Solar System Model).

I’ve always been struck by the opposite point of view. To think that if you hold still enough, and think about it a bit, from one point of view you could be the central reference point for the entire universe, with everything else moving relative to you: the Earth still beneath your feet; the Sun (almost) orbiting around you; and the planets arcing through their epicycles.

Orbits of the inner planets viewed from the Earth (a geocentric perspective). Paths plotted using Gerd Breitenbach's neat little applet.
