What is the heavenly equator?
Heavenly equator is part of a larger system called Heavenly Ball, which is used as a coordinate system for locating and description of the location of heavenly objects. The celestial sphere is not a physical object, but rather an infinite size with the ground in the middle. The heavenly equator corresponds to the Earth's equator and is basically a projection of the Earth's equator to the imaginary heavenly sphere.
The idea of an imaginary line on the imaginary sphere of endless size in the sky can be difficult for many people to understand. For this reason, the representation of heavenly spheres and heavenly equator is often displayed in the teaching of materials that have the size of the set, somewhat larger than the Earth, simply for illustrations. This creates a viewer's perspective looking down at the sphere with the ground in its center. On the sphere of the heavenly equator, the Earth's corresponding path and location.
The Rotation of the Earth causes the heavenly ball to move, but it's not. It is determined on the spot, but the observer moves when the ground turns. This makes the ball turns once every 24 hours, at the same time that the Earth insists to complete one rotation or one day. However, the heavenly equator always appears at the same point from any single place on Earth. This is because the Earth's equator does not move in relation to any point on its surface, and because the heavenly equator is exactly the equator of the earth, nor does it move.
The position of the heavenly equator in the sky will vary, depending on the position of the observer on the surface of the Earth. There will always be a path describing a line that connects with two points, for the east and to the west. When he stands on the equator, it goes through the straightforward. When the observer moves north, the center point of the line moves south. On the contrary, if the observer moves south of the equator, the path of heavenly equator seems to move north. From the perspective of someone standing on one of the two poles, the heavenlyThe equator precisely follows the horizon.
System of the Heavenly Ball -based coordinates is used to locate and quantify the position of objects in the sky. The coordinates for this system are based on declination and proper rise. The king concerns the position of the object above or below the heavenly equator and is measured in degrees. The right rise roughly corresponds to the length, but uses a specific point on the heavenly equator called Vernal Equinox as a reference point. The true rise is measured in lessons, reflecting the apparent rotation of the ball in relation to the ground.
