Pluto has a surface area of about 6.43 million square miles.
About 198 million square miles. The radius of Earth at the equator is about 3963 miles. The surface area of a sphere is given by Area = 4 pi r2, so the surface of the earth is: 4 x 3.14159 x 3963 miles x 3963 miles = 197,359,320.78684 square miles, plus a little extra to compensate for the vertical height of mountains and depth of valleys.
The average distance from Earth to the Moon is about 238,855 miles. This distance is not typically measured in square miles since it is a linear measurement, not an area measurement.
