Ursa Minor Constellation Map
image
Caption: 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.

Hydrus Constellation Map
image
Caption: The constellation Hydrus with its bright stars and surrounding constellations. Hydrus is surrounded by (going clockwise from the top): Eridanus, Phoenix, Tucana, Octans, Mensa, Dorado, Reticulum and Horologium.
Hydrus is a southern constellation and thus the whole constellation is visible in the southern hemisphere at some point in the year. As it lies close to the celestial south pole, only a small part of the northern hemisphere near the equator can see the whole of Hydrus, with other northern equatorial regions able to see parts of the constellation. Hydrus is best viewed in the evenings in the northern hemisphere winter and southern hemisphere summer.
This diagram maps an area around the south celestial pole. Here lines of constant right ascension converge. The right ascension values of these lines are marked on the x-axis above and below the diagram. The solid circle around the pole marks a line of -80° declination with the larger, incomplete circle to the right marking -70° declination. 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.

Octans Constellation Map
image
Caption: The constellation Octans along with its bright stars and its surrounding constellations. Octans is surrounded by (going clockwise from the top): Hydrus, Indus, Pavo, Apus, Chameleon and Mensa. Octans is a relatively faint constellation that is notable as it lies at the south celestial pole. While the northern pole star is the relatively bright Polaris, sigma Octans, the southern pole star, is barely visible with the naked eye.
Octans lies at the south celestial pole and is thus visible from the whole southern hemisphere with some of the constellation visible from equatorial regions of the northern hemisphere. The constellation is circumpolar for most of the southern hemisphere. It is best viewed in the evening in the northern hemisphere autumn and southern hemisphere spring.

Mensa Constellation Map
image
Caption: The constellation Mensa with its brighter stars and surrounding constellations. Mensa is surrounded by (going clockwise from the top): Dorado, Hydrus, Octans, Chamaeleon and Volans. Mensa is a faint constellation with relatively few bright stars.
Mensa lies close to the south celestial pole and thus the whole constellation is visible at some point in the year throughout the southern hemisphere. The whole constellation is visible to a thin strip of the northern hemisphere around the equator with parts of the constellation visible to some other northern equatorial regions. Mensa is circumpolar in temperate, antarctic and some equatorial regions of the southern hemisphere. Mensa is best viewed in the evenings in the northern hemisphere winter and southern hemisphere summer.
The Large Magellanic Cloud (LMC), a satellite galaxy of the Milky Way, lies in Mensa and the neighboring constellation Dorado. The outline of the Large Magellanic Cloud is marked here as a roughly circular loop in green.
This diagram maps an area around the south celestial pole. Here lines of constant right ascension converge. The right ascension values of these lines are marked on the x-axis above and below the diagram. The solid circle around the pole marks a line of -80° declination with the larger, incomplete circle to the right marking -70° declination. 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.

Antlia Constellation Map
image
Caption: 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.
