Difference between Celestial sphere and Sundial

Celestial sphere vs. Sundial

In astronomy and navigation, the celestial sphere is an abstract sphere with an arbitrarily large radius concentric to Earth. A sundial is a device that tells the time of day when there is sunlight by the apparent position of the Sun in the sky.

Similarities between Celestial sphere and Sundial

Celestial sphere and Sundial have 14 things in common (in Unionpedia): Celestial coordinate system, Celestial equator, Celestial pole, Declination, Diurnal motion, Earth's rotation, Ecliptic, Equator, Fixed stars, Latitude, Longitude, Plane (geometry), Sky, Sphere.

Celestial coordinate system

In astronomy, a celestial coordinate system is a system for specifying positions of celestial objects: satellites, planets, stars, galaxies, and so on.

Celestial equator

The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth.

Celestial pole

The north and south celestial poles are the two imaginary points in the sky where the Earth's axis of rotation, indefinitely extended, intersects the celestial sphere.

Declination

In astronomy, declination (abbreviated dec; symbol δ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system, the other being hour angle.

Diurnal motion

Diurnal motion (lit, from dies, lit. "day") is an astronomical term referring to the apparent daily motion of stars around Earth, or more precisely around the two celestial poles.

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.

Equator

An equator of a rotating spheroid (such as a planet) is its zeroth circle of latitude (parallel).

Fixed stars

The fixed stars (stellae fixae) comprise the background of astronomical objects that appear to not move relative to each other in the night sky compared to the foreground of Solar System objects that do.

Sphere

A sphere (from Greek σφαῖρα — sphaira, "globe, ball") is a perfectly round geometrical object in three-dimensional space that is the surface of a completely round ball (viz., analogous to the circular objects in two dimensions, where a "circle" circumscribes its "disk").
