first of all - what is the mass of the earth? imagine that the earth's atmosphere extends beyond the moon's orbit (if you can still call it the atmosphere). so to set a limit, this is still the weight of the earth (including the gaseous envelope) is quite difficult. but - let's assume that we will succeed, or we will agree on some distance - this is still the atmosphere of the earth, this is already interplanetary space. and now - not only em radiation (from the sun, stars) falls on the earth, but also material particles (protons, electrons, ....) and space debris (asteroids and cosmic dust, about 40,000 tons per year). it's not much, but it turns out. and again the air envelope is not a constant mass, but a dynamic space from which not only radiation but also atoms or nuclei of atoms and other particles are released from the atmosphere into the surrounding interplanetary space, even matter can be released directly from the surface ( volcanic eruptions, meterite impacts and subsequent mass ejection, space flights, ...). so we know that part of the mass falls, part of the mass escapes, it clearly follows that the mass of the earth is not constant. this change will certainly not be in the order of percent, but only in small fractions per mille of the earth's mass. Given that the brothel around the earth is more than the earth radiates, we logically conclude that the earth is getting fat, gaining weight. there is exact evidence in this form of complex calculations of the speed of the earth in an orbit in which there are so many variables that we probably won't even understand - only the result is important to us, and it confirms the growing mass of the earth - the result is increasing orbital speed around the sun, from the sun. however, it should be borne in mind that these changes are observable only on a cosmological scale, ie in the order of billions of years.
