The Earth has a mass of 5.98 million billion billion kilograms. That is a big number, but it that will soon change. The Earth is gaining mass, that big number is getting bigger all of time.
Due to small meteors, cosmic dust and assorted interstellar bric-a-brac the Earth takes on a great deal of new material on its passage through the cosmos. Almost all of this debris burns up and falls as dust onto the ground. Said dust causes the earth to gain between 20,000 and 40,000kg each and every day.
