equatorial (right ascension, declination) to geocentric (longitude, latitude)
Please provide values below to convert equatorial (right ascension, declination) to geocentric (longitude, latitude), or change ↔.
equatorial (right ascension, declination)
Definition: A celestial coordinate system used to locate stars and other celestial objects, based on the Earth's celestial equator and the vernal equinox.
Historyandorigin: Originated from the ancient Greeks and was formalized by Hipparchus and Ptolemy. It was later refined by the International Astronomical Union in the early 20th century.
CurrentUse: Commonly used by astronomers for star mapping and locating celestial bodies in the sky.
funfact: The equatorial system is sometimes referred to as the 'astronomical coordinate system' because of its widespread use in astronomy!
geocentric (longitude, latitude)
Definition: A coordinate system based on the center of the Earth as the reference point, measuring positions of objects relative to the Earth’s surface and equator.
Historyandorigin: Historically used by ancient astronomers, it was the standard model for the universe until the heliocentric model was adopted.
CurrentUse: While largely replaced by other models, it is still used for satellite navigation, GPS, and local astronomical observations.
funfact: The geocentric system is tied to Earth's surface, making it practical for terrestrial measurements and navigation!

How to Convert equatorial (right ascension, declination) to geocentric (longitude, latitude)
1 equatorial (right ascension, declination) = 1000000 geocentric (longitude, latitude)
1 geocentric (longitude, latitude) = 0.000001 equatorial (right ascension, declination)
we use cross multiplication method
equatorial (right ascension, declination) → geocentric (longitude, latitude)
1 → 1000000
1.5 → ?( suppose x)
=>1.5*1000000=1*x
by simplifying
x=1500000
