What Does PHA Stand For?
PHA stands for PolyHydroxyAlkanoate Potentially Hazardous Asteroid
PHA, or PolyHydroxyAlkanoate Potentially Hazardous Asteroid, refers to a class of celestial bodies that possess characteristics indicating a potential risk of colliding with Earth, while also being identified by their composition that includes polyhydroxyalkanoates—biodegradable polymers produced by microorganisms. Understanding PHAs is crucial for both planetary defense strategies and the exploration of sustainable materials derived from extraterrestrial resources.
