PERIASTRAL Meaning and
Definition
-
Periastral is an adjective that describes something related to or occurring near a star or stars. It is typically used in astronomy to refer to an object, phenomenon, or event that is in close proximity or has a direct relationship with a star or stars.
In celestial terms, periastral signifies the closest approach or the point of closest proximity between a star and another celestial body, such as a planet or a satellite. This term is often used to describe the orbital mechanics of celestial objects, particularly in the context of binary star systems where two stars orbit around a common center of mass. The periastral point in such systems is when the stars are closest to one another during their orbital revolution.
Alongside its astronomical usage, periastral may also be employed to describe other phenomena that occur in close association with stars. These can range from stellar processes, such as the formation of planetary systems and the birth of new stars, to the effects that stars have on their surroundings. For instance, the periastral region of a star can experience intense radiation, solar winds, or gravitational influences that impact the surrounding gas clouds, debris disks, or nearby celestial bodies.
In summary, periastral refers to anything pertaining to the proximity or direct connection to a star or stars. Whether it is the point of closest approach between celestial bodies or the myriad of interactions that stars have with their surroundings, this term is fundamental to understanding the relationship between stars and the objects or events associated with them.

Etymology of PERIASTRAL
The word "periastral" is derived from two roots: "peri-" and "astral".
1. "Peri-" is a prefix that comes from the Greek word "peri" (περί), meaning "around" or "surrounding". It is commonly used as a prefix to indicate something being situated or located around or near. In this case, "peri-" implies something related to the area around or near celestial bodies.
2. "Astral" also comes from the Greek word "astron" (ἀστρον), meaning "star". It refers to anything related to or associated with stars or celestial bodies.
By combining these two roots, "periastral" is formed, denoting something that is around or near celestial bodies or pertaining to the area surrounding them.
