I was wondering what is happening with Earth accumulating dust and other debris from outer space? This must change earth’s weight? What is the rate of this accumulation of weight? The same thing must be happening to the sun, surely in proportion to the gravity field of the sun, so probably all in all the balance of our planetary system is conserved, in spite the fact everything is getting heavier, but heavier than what? The same thing must happen everywhere else as well, so where can I read something about this?
