Trojan (celestial body) whatever the planet and trojan masses. And if = , then both must exceed 13+√168 ≈ 25.9615. But all this assumes a three-body system: once other bodies are introduced, even if distant and small, stability of the system requires larger ratios. Trojan (celestial body) In astronomy, a trojan is a minor planet or moon that shares the orbit of a planet or larger moon, wherein the trojan remains in the same, stable position relative to the larger object. In particular, a trojan remains near one of the two trojan points of stability – designated and – which lie approximately 60°
Abnormal profit Abnormal profit In economics, abnormal profit, also called excess profit, supernormal profit or pure profit, is "profit of a firm over and above what provides its owners with a normal (market equilibrium) return to capital." Normal profit (return) in turn is defined as opportunity cost of the owner's resources. A related broader term is economic rent, which applies to the owner of a resource, such as land, rather than to the firm as such. According to the theoretical model of perfect competition, abnormal profits are unsustainable because they stimulate new supply, which forces down prices and eliminates the abnormal profit.
