Fundamental plane (spherical coordinates)

In today's world, Fundamental plane (spherical coordinates) has become a topic of great relevance and interest to a wide spectrum of society. Knowing more about Fundamental plane (spherical coordinates) is essential to understand its impact on various aspects of our daily lives. From its influence on the economy to its role in popular culture, Fundamental plane (spherical coordinates) has positioned itself as a central topic in contemporary discourse. In this article, we will delve into the world of Fundamental plane (spherical coordinates) to explore its different facets and its relevance in the current context.

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.
