- MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER A neutron star has a mass of 1.9 x 1030 kg (about the mass of our sun) and a radius of 6.0 x 103 m (about the height of a good-sized mountain). Suppose an object falls from rest near the surface of such a star. How fast would this object be moving after it had fallen a distance of 0.019 m?
