As Earth's mass increase with time due to extraterrestial radiation, would Moon's orbit change?

Answer 1

i do have my difficulties with 'extraterrestial radiation'.
radiation is a sort of energy being present here and there .. like light. soo
earth mass does not increase with radiation.

there's just one form of radiation believed to work here (according to Einstein) that is gravitational waves, which would cause a kind of breaking effect if two codies in space orbit each other. But that is negliable if it comes to the mass relatio of earth and moon.

what in fact hits earth day by day is dust and smaller meteroids and stuff.
This is also not a real thread to the earth/moon system.

In fact if you would guess if there is an increase in earth's mass you would guess it would cause the moon to come closer, i must say, such an effect is not observed.

the moon is slowly escaping, year by year by a few millimeters, and one may need to add 1/8 of moons mass to the earth to see something change.

Answer 2

I doubt that mechanism would cause an appreciable increase in the Earth's mass, but any increase in the mass of the Earth will certainly affect the Moon's orbit.

Answer 3

Cirric is correct - the lunar orbit is slowly increasing as time goes on, because of the tidal force from the Earth. Likewise, this force is causing Earth's rotation to slow. And, the other poster is correct as well - as meteors & dust rain down on Earth (and the moon), the gravitational attraction is increasing, but not enough to counteract the effect of tidal forces.

Answer 4

earth mass is increased by meteors, or any debris from space. moons orbit is decaying. moving away from earth. one day the moon will just keep going. earth will fall apart be cause of the lack of the moons gravity. the wobble that the moon creates will no longer be there. there will be no change in the weather.

Answer 5

Hi. Most of the increase comes form meteors, I think. But the tides are increasing the Moon's orbit by transferring rotational energy.

Answer 6

Yes. However the amount added each day is I believe about 40 tons per day.

the moon is about 8.1x10^19 tons. So this is about 0.0000000000000000049% of the moon's mass each day added to the earth.

EDIT: my original numbers were wrong, sorry. These should be correct.

That's 14,600 tons per year

After 4 billion years, that's 58.4 trillion tons. So that would be 0.0000007% of the moon's mass. Do you think that difference would be noticeable?
