Circumpolar constellation

Index Circumpolar constellation

In astronomy, a circumpolar constellation is a constellation (group of stars) that never sets below the horizon, as viewed from a location on Earth. [1]

Altitude

Altitude or height (sometimes known as depth) is defined based on the context in which it is used (aviation, geometry, geographical survey, sport, atmospheric pressure, and many more).

Astronomy

Astronomy (from ἀστρονομία) is a natural science that studies celestial objects and phenomena.

Axial tilt

In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane.

Azimuth

An azimuth (from the pl. form of the Arabic noun "السَّمْت" as-samt, meaning "the direction") is an angular measurement in a spherical coordinate system.

Camelopardalis

Camelopardalis is a large but obscure constellation of the northern sky representing a giraffe.

Cassiopeia (constellation)

Cassiopeia is a constellation in the northern sky, named after the vain queen Cassiopeia in Greek mythology, who boasted about her unrivalled beauty.

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.

Cepheus (constellation)

Cepheus is a constellation in the northern sky, which is named after Cepheus (a King in the Greek mythology).

Constellation

A constellation is a group of stars that are considered to form imaginary outlines or meaningful patterns on the celestial sphere, typically representing animals, mythological people or gods, mythological creatures, or manufactured devices.

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.

Draco (constellation)

Draco is a constellation in the far northern sky.

Earth

Earth is the third planet from the Sun and the only astronomical object known to harbor life.

Earth's rotation

Earth's rotation is the rotation of Planet Earth around its own axis.

Equator

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

New!!: Circumpolar constellation and Equator · See more »

Horizon

The horizon or skyline is the apparent line that separates earth from sky, the line that divides all visible directions into two categories: those that intersect the Earth's surface, and those that do not.

Latitude

In geography, latitude is a geographic coordinate that specifies the north–south position of a point on the Earth's surface.

North Pole

The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is (subject to the caveats explained below) defined as the point in the Northern Hemisphere where the Earth's axis of rotation meets its surface.

Northern celestial hemisphere

The Northern Celestial Hemisphere, or the Northern Sky, is the northern half of the celestial sphere; that is, it lies north of the celestial equator.

Northern Hemisphere

The Northern Hemisphere is the half of Earth that is north of the Equator.

Polaris

Polaris, designated Alpha Ursae Minoris (Ursae Minoris, abbreviated Alpha UMi, UMi), commonly the North Star or Pole Star, is the brightest star in the constellation of Ursa Minor.

South Pole

The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is one of the two points where the Earth's axis of rotation intersects its surface.

Southern celestial hemisphere

The Southern Celestial Hemisphere, or the Southern Sky, is the southern half of the celestial sphere, which appears to rotate around a polar axis due to Earth's rotation.

Southern Hemisphere

The Southern Hemisphere is the half of Earth that is south of the Equator.
