does our world weigh more or less as time passes?

Answer 1

this is a good question

there are the trivial changes like satellites sent into space, meteors falling on earth, material brought back from the moon, fuel burned on space vehicles.

i believe the above are miniscule in comparison to things like atmospheric evaporation (loss of gasses to space) and radiation to and from the earth. these are very hard to measure and i dont think there is any good data on this issue.

good question

Answer 2

Well, I believe the mass of our planet stays the same (let's hope so, otherwise scientists may decide we're not a planet!)

Technically, the planet weighs a few thousand pounds more than 50 years ago, because of moon rocks brought back with the Apollo. On the other hand, the earth has less weight due to the International Space Station in space.

Other than the above (which is WAY too little to count) no, I believe it stays the same weight.

Answer 3

every year about 50 kilograms are added to the Earth's mass due to comets, meteors and meteorites falling upon us. However this is edged out by the amount of satellite launched annually. There are approximately 800 satellites orbiting the Earth right now.

As we send more and more new materials into space the Earth will become marginally lighter, but not enough so as to effect anything greatly.

I hope I helped :)

Answer 4

erm, given no gigantic impact from an asteroid that would blow up earth, earth is hit by meteorites everyday, most of them discintergrate in the atmosphere but others hit earth. they're just too small to notice and some have hit houses and injured people.

Answer 5

dear emmie, weight of earth is a meaningless que. as weight of anything is differ as grevitation force differ.our weight is not same at space,on earth,on moon , so our world weight is zero in the spece at any time.
