Why didn't the Greeks name all the closest stars?

The ancient Greeks focused on naming the stars that were most prominent and visible to them, often those that formed recognizable patterns or constellations. Many stars were simply too faint to be seen without the aid of telescopes, which were not invented until much later. Additionally, the vast number of stars made it impractical to name them all; they prioritized those that held significance in mythology, navigation, and agriculture. Consequently, many stars remained unnamed or were referred to by their positions or brightness rather than individual names.
