"What if other planetary bodies orbited our world at the same distance as the moon?"
If those larger planetary bodies were at the same distance from our world as the moon, we would be orbiting them, stupid. </trolling>

Ahem. All orbiting bodies orbit around a barycentre between the two objects.
/troll

Interestingly, the barycentre is often inside one of the objects, as in the case of the Earth/Moon. The Sun's barycentre is variable because of the distribution of the mass in the Solar System but it's normally just above its surface.


It depends what you're on about - the 'average' barycentre if there is such a thing? For Jupiter, the barycentre of that orbit is outside the surface of the sun, but for earth it's way inside.

Because of the effect of the planets on the sun, it wobbles around a lot, tugged in lots of directions by the distributed mass around it. Same goes for the earth, if we idealise the orbit to be circular, then even that circle would be a wiggly line as the moon goes around us.

Prof of mine has told me in the past he's had to correct for doppler shift because of that effect!

He's more into Uranus. Phoned that one in.

Surf's up!

yeah, and how did earth orbit EARTH? how many earths does this so called "scientist" want us to think are out there?!>> ^DonanFear:

Nice video but why did he have to animate the rotation? The moon isn't supposed to spin at all when viewed from the Earth and the planets were spinning the wrong way!

Uranus is big


But Uranus isn't even in this vid-- Oh I see what you did there.
