SEMIMINOR AXIS Meaning and
Definition
-
The semiminor axis is a fundamental term in geometry and astronomy that describes an element of an ellipse or an ellipsoid. Specifically, it refers to one-half the length of the minor axis of an ellipse, which is the longest chord (straight line segment) that passes through the center of the ellipse and is perpendicular to the major axis. In other words, it measures the shortest distance between two opposite points on the ellipse that lie on the minor axis.
Similarly, in the context of an ellipsoid, such as the Earth or other celestial bodies, the semiminor axis represents half the length of the shortest diameter that can be drawn between two opposite points on the ellipsoid that lie on the minor axis.
The semiminor axis is of significant importance in mathematics, physics, and other scientific disciplines. Alongside the semimajor axis, it is used to determine various geometric properties of ellipses and ellipsoids, such as their eccentricity, orbital parameters, and differential equations. It plays a crucial role in calculating the shape, size, and orientation of these geometric figures. Additionally, the semiminor axis is utilized in astronomical calculations to define the equatorial radius and polar flattening of ellipsoidal celestial bodies, assisting scientists in accurately representing and modeling their physical properties.

Etymology of SEMIMINOR AXIS
The word "semiminor axis" is derived from the combination of two terms: "semi" and "minor axis".
The term "semi" is a prefix in English that means "half" or "partially". It originates from the Latin word "semi-" meaning "half".
The term "minor axis" refers to one of the two main axes of an ellipse, with the other being the major axis. The minor axis is the shortest distance between two points on the ellipse. The word "minor" is derived from the Latin word "minor", meaning "smaller" or "lesser".
Therefore, when these two terms are combined, "semiminor axis" refers to a line segment that is half the length of the minor axis of an ellipse.
