Kessler Syndrome is a space environmental issue describing how the increasing density of artificial objects in Earth orbit can trigger a self-sustaining cascade of collisions and fragmentation. This concept is based on the possibility that once the density of objects in low Earth orbit reaches a critical threshold, collisions will generate new debris in a chain reaction, rendering the orbit unusable for extended periods. Historical Context The model proposed by Donald J. Kessler and Burton Cour-

Astronomical clocks are complex mechanical timepieces that track astronomical events such as the positions of the Sun, Moon, planets, and Zodiac constellations. Since ancient civilizations, time measurement methods have developed in close connection with the science of astronomy, leading to the emergence of astronomical clocks in medieval Europe. These clocks not only display the time but also model the movements of celestial bodies, allowing the tracking of astronomical events. Especially found
