TROJAN POINT Meaning and
Definition
-
The term "Trojan point" refers to one of the five equilibrium points in celestial mechanics associated with the interaction between three celestial bodies. Specifically, it denotes two points in space that lie along the orbit of a planet or moon. These points are situated approximately 60 degrees ahead (known as the leading or L4 Trojan point) and 60 degrees behind (called the trailing or L5 Trojan point) the smaller body, as viewed from the larger body.
Trojan points are governed by the combined gravitational forces exerted by the two larger bodies on the smaller body. These gravitational forces create a stable region in space where the gravitational forces from both sides of the larger bodies cancel out, thereby allowing the smaller body to stay in a fixed position relative to the larger bodies. As a result, objects placed at Trojan points remain trapped within these regions.
The name "Trojan point" stems from the mythological story of the Trojan War. It derives its name from the Trojan asteroids, which are located at the L4 and L5 Trojan points of Jupiter's orbit around the Sun. These points are the most well-known examples of Trojan points in our solar system.
Trojan points have significant astronomical and scientific importance. They have been discovered in systems with two stars, forming binary star systems, as well as in systems with exoplanets. The study of Trojan points helps astronomers understand the dynamics and stability of planetary systems, providing insights into the formation and evolution of these systems.

Etymology of TROJAN POINT
The word "Trojan" in "Trojan points" comes from the ancient Greek epic, "The Iliad", written by Homer. In the epic, the Greeks besieged the city of Troy during the Trojan War. The term "Trojan" refers to the people of Troy.
The word "point" simply refers to a specific location. In celestial mechanics, "Trojan points" are stable gravitational equilibrium points associated with two celestial bodies orbiting around their common center of mass. These points were named after the Trojans in analogy with the strategic hiding of Greek soldiers inside the Trojan horse during the war.
Overall, the term "Trojan point" combines the references to the city of Troy and the strategic hiding of soldiers in the Trojan horse to denote certain equilibrium points in celestial mechanics.
