What are Trojan Asteroids?

• Asteroids sharing an orbit with a planet, but which are located at the leading (L4) and trailing (L5) Lagrangian points, are known as Trojan asteroids.
• These asteroids occupy a stable Lagrangian point in a planet’s orbit around the Sun.

About Mayan Civilization:

• The Maya are probably the best-known of the classical civilizations of Mesoamerica. 
• Originating in the Yucatán peninsula around 2600 B.C., they rose to prominence around A.D. 250 in present-day southern Mexico, Guatemala, northern Belize and western Honduras.
• Building on the inherited inventions and ideas of earlier civilizations, the Maya developed astronomy, calendrical systems and hieroglyphic writing. 
• The Maya were noted as well for elaborate and highly decorated ceremonial architecture, including temple pyramids, palaces and observatories, all built without metal tools.
• They were also skilled farmers, clearing large sections of tropical rain forest and, where groundwater was scarce, building sizable underground reservoirs for the storage of rainwater. 
• The Maya were equally skilled as weavers and potters and cleared routes through jungles and swamps to foster extensive trade networks with distant peoples.
• The Maya made paper from the inner bark of wild fig trees and wrote their hieroglyphs on books made from this paper. Those books are called codices.
• Their society consisted of many independent states, each with a rural farming community and large urban sites built around ceremonial centers. It started to decline around A.D. 900.
• The Maya peoples never disappeared, neither at the time of the Classic period decline nor with the arrival of the Spanish conquerors and the subsequent Spanish colonization of the Americas. 
• The Maya remain in contemporary Mesoamerican societies and maintain a distinctive set of traditions and beliefs, combined with more recent practices such as the almost total adoption of Roman Catholicism.
