Asteroid impact avoidance
Asteroid impact avoidance, also known as asteroid deflection or planetary defense, aims to prevent dangerous near-Earth objects from hitting Earth, demonstrated by NASA's DART mission in 2022.
Asteroid impact prediction
Asteroid impact prediction is the process of computing near-Earth object orbits and estimating collision probabilities with Earth, carried out continuously by NASA's Sentry and ESA's Aegis monitoring systems.
Asteroid mining
Asteroid mining is the proposed extraction of water, metals, and other materials from asteroids, targeted chiefly at water for rocket propellant; no commercial extraction has taken place yet.
Asteroid occultation
An asteroid occultation is the passage of an asteroid, centaur, or trans-Neptunian object in front of a distant star, briefly blocking its light as the shadow crosses Earth.

Asterousia Mountain Range Biosphere Reserve
Asterousia Mountain Range Biosphere Reserve (Asterousia, Crete), a UNESCO MAB biosphere reserve designated 28 October 2020, Greece's third after Olympus and Samaria; 125,741 ha, Kofinas peak 1,231 m, southernmost mountains in Europe.
Asthenes
Asthenes (canasteros and thistletails) is a genus of Furnariidae ovenbirds established by Reichenbach in 1853, with about 27–30 mostly montane Andean South American species; Schizoeaca and Oreophylax are merged into it, and four species were split into Pseudasthenes in 2010.
Asthenosphere
The asthenosphere is the mechanically weak, ductile layer of the upper mantle directly below the lithosphere, whose low strength lets tectonic plates move over it.
Asthisandhanaka lepa
Asthisandhanaka lepa (Asthi Sandhanak Lep), an Ayurvedic external herbal paste listed as AFI000570, applied for fractures, dislocations, pain, and inflammation; ingredients include Aloe vera, Boswellia serrata, Commiphora myrrha, and Quercus infectoria.

Asthma Control Test
The Asthma Control Test is a five-item patient questionnaire scoring asthma control over the past four weeks, from 5 to 25, with 19 or less indicating poor control.
Asthmatic pulmonary eosinophilia
Asthmatic pulmonary eosinophilia, also called eosinophilic asthma (ICD-11 CB02.0), is pulmonary eosinophilia associated with asthma, classically fungal hypersensitivity to Aspergillus, marked by wheeze, migratory infiltrates, and blood and sputum eosinophilia.

Astigmatism
Astigmatism is a refractive error in which light focuses at two perpendicular lines in the eye, causing blur. Most common refractive error, about 40% adult prevalence; corrected with cylindrical glasses, toric contact lenses, or surgery.
Astigmatism (optical systems)
Astigmatism in optical systems is an aberration in which an off-axis point forms two perpendicular line images instead of one, one of the five Seidel aberrations.
