Difference between Equatorial coordinate system and Hour

Equatorial coordinate system vs. Hour

The equatorial coordinate system is a celestial coordinate system widely used to specify the positions of celestial objects. An hour (symbol: h; also abbreviated hr.) is a unit of time conventionally reckoned as of a day and scientifically reckoned as 3,599–3,601 seconds, depending on conditions.

Similarities between Equatorial coordinate system and Hour

Ecliptic

The ecliptic is the circular path on the celestial sphere that the Sun follows over the course of a year; it is the basis of the ecliptic coordinate system.

Equinox

An equinox is commonly regarded as the moment the plane (extended indefinitely in all directions) of Earth's equator passes through the center of the Sun, which occurs twice each year, around 20 March and 22-23 September.

Hour angle

In astronomy and celestial navigation, the hour angle is one of the coordinates used in the equatorial coordinate system to give the direction of a point on the celestial sphere.

Hour circle

In astronomy, the hour circles, which together with declination and distance (from the centre of mass of the planet) locate any celestial object, is the great circle through the object and the two celestial poles.
