    the moon is moving away from the earth by just under 4 cm a year.

    space 1999 was set on the moon

    Space, "is big. Really big. You just won't believe how vastly, hugely, mindbogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space

    It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds, so the average population of all the planets in the Universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.

    But usually infinity divided by something is still infinity!
    We are still the products of deranged imaginations, but only those of our parents.

    The corresponding effect, arising from tidal energy dissipation, for the Earth-Sun system is very small - about 1 micrometre.

    However, the Sun is losing mass all the time due to nuclear fusion (E=mc^2). This results in just over 1cm increase in separation each year.

    The sun isn't that small, it's just very far away.

    Couldn't be arsed to read the whole thread so if this has had a mention i apologise.

    Jupiter has a magnetic field which spans (about) a million miles from its surface, and if it was a physical structure would be visible from earth.

    The Earth's magnetosphere extends at least 1.25 million km (the magnetotail). The Moon passes through it every month, a couple of days either side of full moon.

    Jupiter's extends out to over 500 million km. During part of its orbital year, Saturn is inside it.

    Uranus' magnetotail is twisted into a corkscrew behind it due to the extreme axial tilt of that planet.

    tbf this is a pre-huygens "fact" so more of a guess than a fact but it's still my favourite :)

    The sound of Titan, recorded on the surface.

    e2a: AFAIK the only recording of sound from the surface of another planet, so far.

    I'm pretty sure they've recorded sound from the surface of Mars.

    Nope. They tried, but there was a faulty system that meant they had to turn the experiment off.
     
  21. EastEnder

    EastEnder Brixton Barnacle

    I stand corrected. They tried to record sound from the surface of Mars.

    It's been tried several times but the Martian curse always seems to strike.

    the chances of any sound coming from mars are a million to one :(

    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.

    you've got the heat/cold on mercury yeah? the one side always facing towards the sun cos of the gravity?

    Yup :) I've just discovered there's a theory that Mercury is actually the core of another planet, gonna look into that and see if I can turn it into something.
    It's a family festival so across the board really, but I suppose I'm aiming for a few years either side of 10. Little worried I've got a bit too technical in places, but hopefully it'll be ok.

    the kids tell me that uranus is tipped on it's side and it has ice rings :)

    Yup, got both of those :) Good to know I'm at least noting the stuff that everyone else finds interesting too :cool:

    It also rotates in the opposite direction to most planets, which caught me out because I thought Venus was the only one that did that.
