Sophia Brahe was a Danish astronomer in the 16th and 17th century who worked with her brother Tycho Brahe, also astronomer, in the creation of a star catalogue that Kepler used as a source to find the laws on the movement of planets in the Solar System. She made the observations on the lunar eclipse of December 1573.

In this context we propose you to solve the following astronomy problem:

Find out the ratio between the surface area of the Earth and the Moon if they are both spheres with a 12,756 km diameter and a 3,476 km diameter, respectively. Study the ratio between their radii and draw your own conclusions.
