The planet has a radius that is 2 times smaller than the radius of the Earth. It is known that the acceleration of gravity on the surface of this planet is the same as on Earth. What is the ratio of the mass of this planet to the mass of the Earth?

The ratio of the planet’s mass to the Earth’s mass is 1: 4, because the acceleration of gravity is inversely proportional to the square of the planet’s radius.
