Has this weight loss been ofset by meteorites etc hitting the earth? By a factor of what?

Woops! thats a good question! how did you come up with that one?

Published estimates of the rate of accretion of meteorites and cosmic dust are mostly in the range of 30 to 60 tons per day. However, in a recent obituary of an international expert on the subject, it said that he believed the rate was about 100,000 tons a year. This is either a misprint, or five to ten times more than anybody else thought.

Estimates are that dust/rocks hitting the Earth are between 5 and 10 tons per day, with events of hundreds of tons every 300-500 years or so...
Easily, the incoming outweighs the outgoing.

No. The earth amasses 40 tons of space debris a day. We barely ship that off in a good year. Plus, some large fraction of what we send into low earth orbit also returns.

The weight of the earth increases tons every day from meteorites ,and dust particles from outer space.

If all the humans went to one side of the Earth and jumped, the Earth's movement is still very insignificant. Besides, we're receiving approximately 50 tons of outer space matter everyday.

Good question, however the loss of mass from the object we launch into space is more than made up my the meteors and meteor dust that the earth picks up every day.

The Earth weighs 6,000,000,000,000,000,000,000 tonnes.
Do you really think it makes any difference?
It would be relatively less than the weight you would lose when a single flake of dandruff falls off your head.

We get tons and tons of space debris adding to our weight every day. We probably get more in a month then we've sent up in 45 years or so.

solar dust/particles fall to earth each year by the TON..it easily covers what is sent to space, in fact it falls in such great quantity that it add to the earths weight

the earth's weight isn't dictated by what is on it.
the only way it would is if the earth itself was held down by some other gravitational force(other than the sun when it is held in orbit by centrifugal force)
