The Fundamental plane (spherical coordinates) issue is a matter of great importance that impacts the lives of millions of people around the world. This is a complex and multifaceted issue that covers a wide range of aspects, from the personal to the global level. In this article, we will explore different perspectives and approaches related to Fundamental plane (spherical coordinates), analyzing its relevance today and reflecting on its long-term implications. Through detailed and rigorous analysis, we will attempt to shed light on this topic and provide the reader with a deeper and more complete 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.
