Stars in other galaxies also have the property of forming various systems from groups to clusters.
The distances in groups of stars are extremely different[^ref-41]: from close pairs (\\(10^{12}\\) cm) to wide pairs (\\(10^{17}\\) cm). There are two types of clusters: globular and diffuse. The diameters of scattered clusters[^ref-42] range from 6 - \\(10^{18}\\) cm to \\(10^{20}\\) cm, and the number of stars in them from 20 to 2,000. Globular clusters have more stars: from \\(10^{5}\\) to \\(10^{7}\\), and their diameters range from \\(10^{19}\\) to \\(10^{20}\\) cm.

Globular clusters have more stars: from \\(10^{5}\\) to \\(10^{7}\\), and their diameters range from \\(10^{19}\\) to \\(10^{20}\\) cm.
Thus, the extremely large star clusters have a size of \\(10^{20}\\) cm, which is exactly 10 orders of magnitude larger than the smallest stars.
> It may seem that the author has arbitrarily limited stellar systems to clusters, since galaxies also consist of stars. However, the point is that a galaxy as a type of system differs from a star cluster in several fundamental respects.

More massive stars (with masses between 1.2 and 2.0 solar masses) explode as supernovae and their cores shrink to neutron stars (NSs), with average size estimates close to \\(10^{7}\\) cm.
The most massive stars (with masses greater than two solar masses) can form black holes (BHs) after the explosion; their sizes are estimated[^ref-45] from 3 - \\(10^{5}\\) to \\(10^{7}\\) cm.

All of these objects are fundamentally different in their properties from ordinary stars. First, they no longer consist of atoms, but of their nuclei or elementary particles. Second, their radiation energy is no longer associated with thermonuclear synthesis, the main energy source of stars. The luminosity and color of these objects are also completely different from the luminosity and color of ordinary stars.
