What are the elements of spherical astronomy?
The primary elements of spherical astronomy are celestial coordinate systems and time.
The coordinates of objects on the sky are listed using the equatorial coordinate system, which is based on the projection of Earth's equator onto the celestial sphere..
What is spherical Trignometry in astronomy?
Spherical trigonometry involves the study of spherical triangles, which are formed by the intersection of three great circle arcs on the surface of a sphere.
Spherical triangles were subject to intense study from antiquity because of their usefulness in navigation, cartography, and astronomy..

Spherical triangles were subject to intense study from antiquity because of their usefulness in navigation, cartography, and astronomy..
What is spherical trigonometry used for?
Spherical trigonometry is of great importance for calculations in astronomy, geodesy, and navigation..
What is the meaning of spherical astronomy?
Spherical astronomy, or positional astronomy, is a branch of observational astronomy used to locate astronomical objects on the celestial sphere, as seen at a particular date, time, and location on Earth.
It relies on the mathematical methods of spherical trigonometry and the measurements of astrometry..
What is the sphere in astronomy?
celestial sphere, the apparent surface of the heavens, on which the stars seem to be fixed.
For the purpose of establishing coordinate systems to mark the positions of heavenly bodies, it can be considered a real sphere at an infinite distance from the Earth..
What is the spherical angle in astronomy?
The spher- ical angle can also be defined as the angle between the tangents (PA0,PB0) to both arcs of great circle in their intersection point.
Elements: The sides of the spherical angle are the arcs of great circle and, in their intersection, we have the vertex..
Who found spherical trigonometry?
Menelaus of Alexandria (ca. 100 AD) wrote in three books his Sphaerica.
In Book I, he established a basis for spherical triangles analogous to the Euclidean basis for plane triangles..
Why do we use spherical geometry?
Spherical geometry is useful for accurate calculations of angle measure, area, and distance on Earth; the study of astronomy, cosmology, and navigation; and applications of stereographic projection throughout complex analysis, linear algebra, and arithmetic geometry..
A triangle drawn on the surface of a sphere is a spherical triangle if it has all of the following properties:
The three sides are all arcs of great circles.Any two sides are together greater than the third side.The sum of the three angles is greater than 180\xb0.Each spherical angle is less than 180\xb0.- Spherical geometry is useful for accurate calculations of angle measure, area, and distance on Earth; the study of astronomy, cosmology, and navigation; and applications of stereographic projection throughout complex analysis, linear algebra, and arithmetic geometry.
