ABBREVIATION for New General Catalogue of Nebulae and Clusters of Stars; a catalogue in which over 8000 nebulae, galaxies, and clusters are listed numerically 星群总录
If the center of NGC 4258 were a star cluster, the stars would be so closely spaced that collisions between individual stars would have long ago torn the cluster apart.
如果 NGC 4258 的中心是一个星团，恒星之间的距离会非常近，以至于在很久以前单个恒星之间的碰撞就会把星团撕裂。
