ASTROMETRIC Meaning and
Definition
-
Astrometric is an adjective used to describe the field of astrometry, which is the branch of astronomy focusing on the precise measurement of celestial objects in terms of their positions, distances, and motions in space. Astrometrics aims to accurately determine the coordinates of celestial bodies, enabling the construction of comprehensive star catalogs and facilitating the study of their behavior over time.
In the context of astrometry, astrometric measurements typically involve the use of specialized telescopes and instruments for accurate observations. These measurements are vital for assessing the physical properties of celestial objects, such as their size, mass, and velocity, as well as their interactions with other objects in the universe.
Astrometric techniques often rely on the principle of parallax, which measures the apparent shift in the position of a celestial body when seen from different points in space. By triangulating the parallax angle, astronomers can derive accurate distance measurements to stars and other cosmic objects.
Furthermore, astrometric calculations are crucial for the detection and study of extrasolar planets by employing the method of astrometric transit or by detecting the gravitational wobble induced by these planets on their host stars.
Overall, astrometric measurements provide valuable information that contributes to our understanding of the structure, composition, and dynamics of the universe, offering insights into the fundamental laws governing celestial objects and the evolution of galaxies and stellar systems.

Etymology of ASTROMETRIC
The word "astrometric" is derived from the combination of the prefix "astro-" and the suffix "-metric".
1. "Astro-" comes from the Greek word "astron", meaning "star" or "heavenly body". It is commonly used as a prefix in English to denote something related to astronomy or celestial objects.
2. "-Metric" is derived from the Greek word "metron", which means "measure" or "measurement". It is frequently used as a suffix to indicate the act of measuring or the study of measurement.
Therefore, the word "astrometric" refers to the measurement or study of the positions, distances, and movements of celestial objects, particularly stars.
