乍看之下，中子星就是一个巨大的原子核。不同的只是，中子星是由引力来维持的，原子核则依靠核力。在中子星内，在只不过是几公里的距离上，引力是如此之强，它能把物质固定在非常确定的结构中。主要表现之一是表面上的所有不规则性都被消除，中子星上最高的山峰只有几厘米高
At first glance, the neutron star is a huge atomic nucleus. The difference is that the neutron stars are maintained by gravity, while the atomic nuclei depend on nuclear forces. Within a neutron star, gravitational force is so strong at a distance of just a few kilometers that it can fix matter in a very definite structure. One of the main manifestations is that all the irregularities on the surface are eliminated. The highest peak on the neutron star is only a few centimeters high.
