• Adeona — A goddess in archaic Roman mythology protecting children and travelers, structurally invoked to ensure the safe return home of those who departed. In modern astronomy, the term designates 145 Adeona, a large and dark asteroid from the main asteroid belt, discovered in the 19th century by Christian Peters and considered the parent body of a distinct collisional family of asteroids.
• Aerolite — A meteorite composed mostly of silicate mineral substances (stony), sometimes exhibiting small metallic inclusions of iron and nickel. This category of celestial bodies that have fallen onto the Earth's surface is structurally divided into chondrites and achondrites, offering fundamental scientific data regarding the early composition of the solar system.
• Airy — A proper name of global scientific resonance, dedicated to the English astronomer and mathematician Sir George Biddell Airy; it denotes a multitude of concepts, mathematical functions, optical phenomena, and planetary landmarks. These include the Airy functions (solutions to linear differential equations), the Airy disk and associated diffraction pattern (essential for setting microscopic and telescopic limits), the Airy crater on Mars (which defines the zero meridian of that planet), as well as a fundamental theory of Earth's crustal isostasy.
• Areology — A branch of planetary astronomy and planetary geology that deals with the complete structural and morphological geological study of the planet Mars. This scientific discipline analyzes the chemical composition of the Martian soil, internal rock structures, topography, impact craters, volcanic evolution (such as Olympus Mons), and polar ice cap dynamics, representing the Martian equivalent of terrestrial geology.
• Astrogeology — An interdisciplinary branch of planetary science and geosciences that deals with the study of the geological structure, chemical composition, morphology, mineralogy, and evolutionary history of solid celestial bodies in the Solar System, such as terrestrial planets, their natural satellites, asteroids, comets, and meteorites. This field utilizes orbital remote sensing techniques, spectrographic analysis, and direct examination of extraterrestrial rock samples (such as lunar or Martian samples).
• Astronomy — A fundamental and natural science that deals with the study, observation, measurement, and physico-mathematical interpretation of celestial bodies (stars, planets, satellites, comets, asteroids, galaxies), cosmic structures, and the universe as a whole. This discipline investigates the origin, evolution, chemical composition, and motion dynamics of matter and energy in extra-atmospheric space, being one of the oldest branches of human knowledge.
