Schiehallion Mountain, in Perthshire, which is located in Scotland; which helped the astronomer calculate the mass of the Earth.
Maskelyne set out to calculate the mass of the mountain and with his findings he wanted to determine the mass of the Land with more precision, since I use the radius of the Earth to calculate its volume and thus predict in the most precise way the density of our planet at that time. The importance of knowing how much did the earth weigh It could allow scientists to predict the relative bad fortunes of every object in the universe such as the Sun.
Maskelyne He asked that observation stations be built on the slopes of the mountain and a pendulum was placed, dragged towards the center of the Earth by the gravitational force of this planet. This mountain that she chose to oversee Maskelyne personally would later become one of the most famous attractions in the region with more than 20 thousand hikers who would travel its slopes each year.

The importance of knowing how much the Earth weighed could allow scientists to predict the relative health of each object in the universe, such as the Sun.
In 1775, the astronomer presented his results to the Royal Society (Earth weighed 5.972 × 10^24 kg) and according to the BBC, the estimates it presented were within 20% of the mass the Earth is believed to have.
