But usually infinity divided by something is still infinity!...not every one of them is inhabited. Therefore, there must be a finite number of inhabited worlds...
the moon is moving away from the earth by just under 4 cm a year.
Jupiter has a magnetic field which spans (about) a million miles from its surface
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.

I'm pretty sure they've recorded sound from the surface of Mars.The sound of Titan, recorded on the surface.
e2a: AFAIK the only recording of sound from the surface of another planet, so far.
Nope. They tried, but there was a faulty system that meant they had to turn the experiment off.I'm pretty sure they've recorded sound from the surface of Mars.
I stand corrected. They tried to record sound from the surface of Mars.Nope. They tried, but there was a faulty system that meant they had to turn the experiment off.

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.you've got the heat/cold on mercury yeah? the one side always facing towards the sun cos of the gravity?
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.i can check with kid2 if you like: she got a glow in the dark solar system to hang in her bunk bed for her birthday
