What is the weight of the planet Earth? Is it constant or increasing?

Not weight but mass of the planet Earth is approximately 6E+24 (Six followed by twenty four zeros!) kilograms. The weight of the object would differ in different gravitational fields. For example, in Earth’s gravitational field some object weighs, say, 1 kilogram, then the same object on the Moon (i.e. in the Moon’s gravitational field) would weigh 1/6 of its weight on the Earth. That is the reason the weight of the planet can’t be talked about because it requires a gravitational field to determine weight. The mass remains the same.

However, you will be surprised to know that the weight of our planet increases approximately by 20,000 to 30,000 tons a year!

Being in swift motion in the space the Earth attracts into its atmosphere space dust, little special objects and falling stars with its gravitational force. Even if these objects burn out due to friction of the atmosphere, the ashes keep on adding in good to the weight every day. Although, this quantity being added is nothing in relation to the total weight of the planet.
