If the radius of Cosmo is equal to 2Re, the gravitational field strength at Cosmo's surface is equal to that at Earth's surface.

What is the Earth's radius?

The Earth's radius, as measured by 183 high school students involved in the World Year of Physics project "Measure the Earth with Shadows," is 6563 km, as opposed to the commonly accepted figure of 6371 km for the mean radius.

Is the Earth's radius 6400 kilometres?

About ten times as much mass as Mars is the Earth. If an object weighs 200 N on Earth's surface, it will weigh similarly on Mars.
