A few interesting things


The dew on a cow's nose fertilizes the grass while they graze.
Cows fur produces vitamin D, which they then lick off and use.
Most clover in a field will be connected by the roots, if one part gets overgrazed the rest will produce a mild form of arsenic.

Feel free to add your own interesting tidbits! emoticon

I did not know that about cows' noses! Cool!

Antarctica is the driest place on Earth;
The highest mountain in the known universe is on Mars; and
The Earth has at least seven moons.

But... the Earth only has 3 moons!

Luna
Cruithne
and one so small it just has a code "AA29" the poor thing... emoticon

I suspect aside of Luna, the others aren't true moons really... for instance looking up Cruithne indicates that it's a quasi sattellite, something that has a 1:1 orbital resonance with Earth, but doesn't actually orbit it. I don't know what AA29 is, but is it something similar?

In any case... the reason for this is because I believe Luna will tend to chuck anything that tries orbitting around Earth eventually, as such there isn't much scope for there being a stable spot for further moons. And of course one could try arguing if even Luna is a true Moon, in some senses it's more like a double planet setup and only getting called a Moon due to it falling just short on technicalities. (Though I do believe that eventually once the Moons orbit widens far enough, that the definition will switch it from Moon to Planet automatically; this event is obviously a long time in the future still though)

AA29 has a very weird orbit so that once every 1000 years or so it actually does become a bona fide moon of the Earth for about 50 years before deciding to go wander around some more. The next time that happens won't be til 2600AD so I have my camera on a timer to capture the event. emoticon

Ahh, good plan, you might forget to take a picture at the time otherwise. emoticon

Re: A few interesting things


Interesting! I'd never run into AA29 before. You're right, it's not what anyone would really call a "moon" or "satellite" of the Earth. Apparently the correct term is "cosatellite", since it revolves around the Sun at about the same distance and at a harmonically-locked period as the Earth. But while it's close to us now, it's "running away" from the Earth. In ~47 years, it'll be on the far side of the Sun from us (ie: half a year out of phase), and in ~95 years, it'll have "run away" so far that it actually laps us and almost catches up from behind! But then Earth's gravity will give it a shove and get it going again in reverse, making the revolve around the Sun slightly slower than us.

AA29 is a good example of an N-body gravitational problem. If I'd known about it, I'd have tried to replicate it when I had that old homework assignment back in grad school!
