Your favourite Solar System facts

Mercury and Uranus are buggers to find facts for :mad: Well, facts that can be expanded upon for more than a sentence, but will still interest kids.
Mercury is the only other rocky planet with a strong magnetic field. And if you factor out the effects of gravitational compression, Mercury is the densest planet in the solar system (Earth is denser, but only because of its greater gravity, not because the stuff its made of is actually denser).

Uranus sounds like a bum hole.
 
You could always point out that, once they've got to the thousand yard point, if they wanted to walk to the Oort cloud it would be around a thousand miles away. The extent of the Sun's gravitational influence is roughly three thousand miles, and the nearest star six thousand miles. I'm doing the maths in my head badly, but that seems about right.
 
The apparently rare phenomenon known as life exists on the third planet from the sun. It's really quite remarkable.
 
The Sun's distance from the Earth is about 400 times the Moon's distance, and the Sun's diameter is about 400 times the Moon's diameter. Because these ratios are approximately the same, the Sun and the Moon as seen from Earth appear to be approximately the same size and we get eclipses.

Only for about the next 700,000,000 years. ;)
 
But by then stellar evolution will have made life on earth impossible anyway :p

Perhaps, roughly then (assuming some other major impact event or eruption or local supernova doesn't curb life first) but bacteria and viruses may well soldier on for a few more hundred million years until a combination of processes eliminate all planetary water.
 
Helium (the second most common element in the universe after Hydrogen) was discovered in the Sun before it was found on Earth.

In 1868 Joseph Lockyer using a spectrometer attached to a telescope pointing at the Sun, found a line in the yellow region of the solar spectrum to which no match could be found. He named it Helium after Helios (Greek for the Sun). It was not until 25 years later that William Ramsey extracted Helium from the mineral clevite.
 
Ooh, cheers, that does look interesting :)

Thanks for the help everyone, Make Merry was held over Jubilee weekend and was generally regarded as a big success :) Already planning for next year... :cool:
 
I volunteer for a local family festival (the Plumstead Make Merry, if yer interested ;)) and one thing we'd like to do this year is have a go at the 1'000 yard model of the Solar System. The basic idea is you recreate the Solar System to scale over roughly 1,000 yards.

At each of the markers for the different planets we hope to have an A3 sign giving details and facts about the planets. Obviously we'll have the standard stuff of size, distance from the Sun, etc, but I'm really keen to have some really fun and interesting facts. For example, Saturn is so light that if you were to have a bathtub big enough, it would float in the water! (Shamelessly nicked from Kidzone)

What other facts will interest and amuse the kids of Plumstead, and make their little jaws drop at the awe-inspiring wondrousness of the Solar System?

This is real.
 
Coupled with the difficulties of washing proerly in zero-G, the space station apparently reeks
Do astronauts wank while they're in the ISS? The logistics must be tricky, but surely they can't live up there for six months and not feel the need sometimes. Would make a hell of a mess though.

Ickle sperms floating about are nothing compared to when you pull your pants down to hilariously let rip a massive fart but it turns out to be liquid.

Might be difficult for the fellas. As I understand it ones blood pressure drops quite a bit in prolonged micro gravity. Could be done I suppose, but you'd be a bit soft.
