Ursa Minor Constellation Map
صورة
الشرح: The constellation Ursa Minor along with its bright stars and its surrounding constellations. Ursa Minor is surrounded by (going clockwise from the top): Cephus, Camelopardalis and Draco. Ursa Minor is notable as its brightest star, Polaris is the northern pole star.
Ursa Minor is visible from the entire northern hemisphere with some parts of the constellation being visible from equatorial regions of the southern hemisphere. It is also circumpolar for temperate and arctic regions of the northern hemisphere. Polaris, lying very close the north celestial pole is circumpolar for the whole of the northern hemisphere. The constellation is most visible in the evenings in the northern hemisphere summer and southern hemisphere winter.
This diagram maps an area around the north celestial pole. Here lines of constant right ascension converge. The right ascension values (in hours) of these lines are marked on the x-axis above and below the diagram. Some of the lines of constant declination (in degrees) are marked on the y-axis. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. Neither the constellation boundaries, nor the lines joining the stars appear on the sky.

Antlia Constellation Map
صورة
الشرح: The constellation Antlia along with its bright stars and surrounding constellations. Antlia is surrounded by (going clockwise from the top): Hydra, Pyxis, Vela and Centaurus.
Antlia is a southern constellation that is visible at some point in the year from the whole southern hemisphere as well as equatorial and some temperate regions of the northern hemisphere. The constellation is best viewed in the evenings in the northern hemisphere spring and southern hemisphere autumn.
The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. Neither the constellation boundaries, nor the lines joining the stars appear on the sky.

Boötes Constellation Map
صورة
الشرح: The constellation Boötes with its bright stars and surrounding constellations. Boötes is surrounded by (going clockwise from the top): Draco, Ursa Major, Canes Venatici, Coma Berenices, Virgo, Serpens Caput, Corona Borealis and Hercules. It is notable for its brightest star Arcturus which is the fourth brightest star in the night sky.
Boötes is a northern constellation and the whole constellation is visible to the entire northern hemisphere at some point in the year. Parts of the constellation are visible from all but the most antarctic parts of the southern hemisphere but the whole constellation is only visible from equatorial and some temperate parts of that hemisphere. Boötes is most visible in the evenings in the northern hemisphere summer and southern hemisphere winter.
The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars.

Caelum Constellation Map
صورة
الشرح: The constellation Caelum with its bright stars and surrounding constellations. Caelum is surrounded by (going clockwise from the top): Eridanus, Horologium, Dorado, Pictor, Columba and Lepus. Caelum is a relatively small and faint constellation.
Caelum is a southern constellation and the whole constellation is visible at some point in the year from the whole southern hemisphere and from equatorial parts of the northern hemisphere. Parts of the constellation are visible from temperate regions of the northern hemisphere. The constellation is most visible in the evenings in the northern hemisphere winter and southern hemisphere summer.
The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars.

Canis Minor Constellation Map
صورة
الشرح: The constellation Canis Minor with its bright stars and surrounding constellations. Canis Minor is surrounded by (going clockwise from the top): Gemini, Monoceros, Hydra and Cancer. Canis Minor has relatively few bright stars but its brightest star Procyon is the eight brightest star in the sky.
Canis Minor spans the celestial equator and thus part of the constellation is visible from the whole Earth at some point during the year. The whole constellation is visible to all but the most arctic and antarctic regions.
The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. The blue line in the top right of the diagram marks the ecliptic. Neither the constellation boundaries, nor the line marking the ecliptic, nor the lines joining the stars appear on the sky.
