Our Solar System is NOT a “Vortex”

I’ve been getting lots of tweets and email from folks linking to a slick-looking video, a computer animation showing the motion of the planets around the Sun as the Sun orbits around the Milky Way Galaxy. It’s a very pretty video with compelling music and well-done graphics.

However, there’s a problem with it: It’s wrong. And not just superficially; it’s deeply wrong, based on a very wrong premise. While there are some useful visualizations in it, I caution people to take it with a galaxy-sized grain of salt.

Why? The basis of the claim is that the planets aren't orbiting the Sun heliocentrically, but are instead a vortex going around the galaxy.

Normally I wouldn’t bother debunking stuff like this; wacky claims are made all the time and usually disappear on their own. But in this case I’m getting a lot of people telling me about it, so clearly it's popular—probably because it seems superficially right, and it has very nice graphics. I’m also seeing it spread around by people who do understand science, but missed the parts of it that are way off. With stuff like this, it always pays to dig a little deeper.
