For more on marking an answer as the "Best Answer", please visit our FAQ.The answer that brachiopod gives for the weight of the moon is only true if it was to be brought down to earth and weighed here. Assuming you has some scales big and strong enough.
The gravity at the moon's surface is only one sixth of the earth's gravity and if the moon was weighed there, it would only weigh one sixth as much as brachiopod says. Only trouble with that is that not all of the moon's mass is on its surface and its gravity will decrease to zero at its core - and hence its weight will too.
If you were to take the moon to Jupiter and weigh it there, then it would weigh around 2.6 times as much as on earth.
brachiopod,
Shouldn't we be trying to answer the question asked by the poster? Pixi clearly asked for the weight of the moon, not its mass. The answers that you and Clanad were giving were the MASS of the moon. I was merely trying to tell pixi something about the WEIGHT of the moon, - as she requested.
Ok.....
Pixi, if you were to bring the Moon down to Earth to sell, it would have a 'weight' greater than 735,400,000,000,000,000,000,000 Newtons, since the extra mass of the Moon on the Earth would increase the force of gravity on Earth, and therefore it would 'weigh' a bit more than this figure.
I haven't got time to work the exact figure, as I have to pop down to Morrisons before it closes to buy approximately 5 newtons of Mature Cheddar for my supper.
Hi Pixi, well the boys are squabbling again, and I want to say that I think your question is REALLY sensible.
Do you realise that Newton delayed the publication of his theory (of whatever) for around 20 years because his estimate of the mass of the moon (or was it the earth) didnt tally with the forces and so on ? - so he couldnt get them to add up so to speak.
I agree that Newton did not use the words "green cheese", but that, Pixi, is not your fault.
