Fundamental plane (spherical coordinates)

Since time immemorial, Fundamental plane (spherical coordinates) has been the subject of fascination, study and debate. Its impact has transcended all cultural, geographical and temporal barriers, leaving an indelible mark on the history of humanity. From the remotest reaches of the past to the most immediate present, Fundamental plane (spherical coordinates) has been an object of adoration, analysis, and contemplation. In this article, we will explore in depth the many facets of Fundamental plane (spherical coordinates), unraveling its meaning, its influence and its relevance in today's world. Throughout the pages that follow, we will embark on a fascinating journey through history, science, culture and society, in search of a more complete and enriching understanding of Fundamental plane (spherical coordinates).

Plane of reference that divides the sphere into two hemispheres

For the concept in extragalactic astronomy, see Fundamental plane (elliptical galaxies).

The fundamental plane in a spherical coordinate system is a plane of reference that divides the sphere into two hemispheres. The geocentric latitude of a point is then the angle between the fundamental plane and the line joining the point to the centre of the sphere.

For a geographic coordinate system of the Earth, the fundamental plane is the Equator.

Astronomical coordinate systems have varying fundamental planes:

• The horizontal coordinate system uses the observer's horizon.
• The Besselian coordinate system uses Earth's terminator (day/night boundary). This is a Cartesian coordinate system (x, y, z).
• The equatorial coordinate system uses the celestial equator.
• The ecliptic coordinate system uses the ecliptic.
• The galactic coordinate system uses the Milky Way's galactic equator.
