CELESTIAL HORIZON Meaning and
Definition
-
The celestial horizon is an imaginary boundary that separates the visible sky from the Earth's surface. It is a fundamental concept in astronomy and refers to the apparent meeting point of the Earth and the sky when observed from a specific location on the ground. This line forms a perfectly circular boundary around an observer, dividing the sky into two hemispheres: the visible hemisphere above the horizon and the invisible hemisphere below it, also known as the sky's dome.
The celestial horizon is determined by the observer's position, latitude, and altitude. It represents the lowest point in the sky where celestial objects, such as stars, planets, the Moon, and the Sun, can be seen. Any object that appears below the celestial horizon, or has not yet risen above it, is considered to be below the observer's horizon and is invisible from that specific location at that particular moment.
The concept of the celestial horizon is used to describe various astronomical phenomena, including sunrise and sunset, as well as the rising and setting of celestial bodies. It serves as a key reference point for astronomers and navigators alike, aiding in the determination of directions, celestial coordinates, and celestial navigation. Understanding the celestial horizon is crucial for anyone studying or observing the heavens, as it provides a fundamental frame of reference for their observations and interpretations in relation to the Earth's surface.
