Our planet weighs 5.97 billion trillion tons. A mass that is hardly imaginable by our brain but which in reality constantly undergoes substantial changes and which over the centuries will no longer be the same.
There is a lot of research on this topic and it estimates that with the accumulation of meteor dust and space debris of all kinds, our planet gains 40 thousand tons every year. On the other hand, however, the atmosphere disperses 95,000 tons of hydrogen into space every year.

Then there are various other phenomena that together constitute a constant loss of mass for the planet. The radioactive decay of the nucleus is 160 tons per year and the loss of helium into the atmosphere is 1600 tons per year.
In all, we arrive at approximately 50 thousand tons of weight every year. A number that seems scary and brings to mind the image of a planet that slowly loses pieces until it vanishes.
In fact, according to scientists’ calculations, it takes about 120,000 trillion years for our “home” to disappear. A number that shouldn’t affect us as a species. And certainly until next weekend we can rest assured.
