The Earth weighs around 6,000,000, 000,000,000,000,000,000 Kg

Bit of a science one this time the Earth weighs 6,000,000, 000,000,000,000,000,000 Kg ! how do we know this ? Good question everything that has a mass has a gravitational attraction to each other so if you put two weights together they will attract each other now this will be a very small attraction but if you have instruments sensitive enough you will be able to read this. From this attraction you can work out the mass of the objects. It is worth mentioning that having a weight is reliant on a gravitational field it is more accurate to state this weight as the mass of the Earth as this will not change depending the strength of the gravitational field.
