Here's the Galaxy.

Just about all of it!

It's like google-maps, zoom in, scroll, check out the neighborhood.

Hey, I can see my house from here!

Here's Sixty Symbols telling us about orbital precession.

Very fun youtube channel!

Pretty cool orbit animation that produces a tone every time a planet completes an orbit. Makes interesting "solar song".

That is way cool. It really shows how slow Pluto's orbit is compared with the inner planets.
Could be described as the music of the spheres.



My thought exactly. :)

This thread is amazing. Loss of productivity? Only for about the rest of my life exploring all these links. :? Thanks to everyone who has posted here. :wink:

Thanks Johnson, a good short simple introduction to the physics. Love the way he puts blue tack around the earth's equator to show the spare tire we are carrying, like spinning a pizza base to thin it out. If earth wasn't such a fattie there would be no precession of the equinox.

Wow Johnson, that is just superb.

I used it to make this picture of the apparent geocentric orbits, showing the epicycles of Jupiter. It shows how the movement of the planets appears to us from earth, with the annual retrograde motion causing the loops as earth speeds past the outer planets. Jupiter gets back to its original position after 11.85 years, and by turning on tracing you can see this picture of nearly six years of Jupiter's apparent motion.

More internet shenanigans. Despite having been viewed more than 600 times, I can't see the picture attached to this post. Here it is again. Can other people see it?

This is not a link to an orbital simulator, but it does really nicely describe what exactly the lagrange points are, and how their orbits would look.

Good stuff!

What if the Moon's orbit was the same as that of the ISS?

http://www.wimp.com/moondistance/

In this animation the moon appears to be traveling the exact path as that of the ISS, with the earth in its regular orbit. In reality with the earth and moon so close to one another our orbits would be a lot weirder. Stable orbits have to speed up as they approach the source of gravitation. The pull of gravity increases inversly as the square of the distance, so 2 times further away means 4 times weaker gravity. And the opposite is true when coming closer. So that means the moon has to go faster. And that also means the earth would be wobbling like crazy, and the tides would be..... tsunami style.

Johnson, maybe you can help with this. There was a thread regarding why planets orbit in the same direction, on the same plane. I couldn't find it to post this video. There's an interesting example at 3 minutes in.
