Consider a neutron star whose mass is twice the mass of the Sun and whose radius is 14.1 km. If it rotates with a period of 1.89 s, what is the speed of a point on the Equator of this star? What is the value of g at the surface of this star? Compare the weight of a 1.10 kg mass on the Earth with its weight on the neutron star. How many times bigger is this mass on the neutron star than on Earth? If a satellite is to circle 14.1 km above the surface of such a neutron star, how many revolutions per minute will it make?

What is the radius of the geostationary orbit for this neutron star?
