Our planet weighs 5.9 sextillion tons (or 5,972,000,000,000,000,000,000). In truth, O right It is «mass», since «Weight” It is O result from the gravitational pull of a larger object (usually itself Earth) about a minor. Calculate the mass of our planet It is an old challenge: in 1737, the expedition of the French scientist Pierre Bouguer used O period of oscillation of a pendulum, which varied with gravity at different altitudes, to make an estimate. O number he arrived at It is almost three times larger than O current value. Several experiments were carried out throughout the 18th century until reaching 5.9 sextillion, calculated by British physicist Henry Cavendish in 1797.
