Mountains on Neutron Stars Only Fractions of Millimeters Tall Due to Intense Gravity

“Mountains” on Neutron Stars Only Fractions of Millimeters Tall Due to Intense Gravity Incredibly dense stars weigh as much as our sun but only the size of a city. Image Credit: Share Email The research is presented today at the National Astronomy Meeting 2021. Neutron stars are some of the densest objects in the Universe: they weigh about as much as the Sun, yet measure only around 10km across, similar in size to a large city. Because of their compactness, neutron stars have an enormous gravitational pull around a billion times stronger than the Earth. This squashes every feature on the surface to miniscule dimensions, and means that the stellar remnant is an almost perfect sphere.
