Rosalinda wants to calculate the mass of Earth using Kepler’s laws or Newton’s universal law of gravitation.Which data would allow her to find the mass of Earth?

For an object orbiting Earth, Newton’s version of Kepler’s third law relates Earth’s mass to the moon’s orbital period and its average distance from Earth: M = 4π²r³/(GT²). So Rosalinda needs both the moon’s orbital period and its distance from Earth. The Sun’s mass and Earth’s orbit describe Earth’s motion around the Sun, not the moon’s orbit around Earth.
