Southern celestial hemisphere

In the context of astronomical discussions or writing about celestial mapping, it may also simply then be referred to as the Southern Hemisphere.

[citation needed][dubious – discuss] In large cities, about 300 to 500 stars can be seen depending on the extent of light and air pollution.

[citation needed] The brightest star in the night sky is located in the southern celestial hemisphere and is larger than the Sun.

Sirius in the constellation of Canis Major has the brightest apparent magnitude of −1.46; it has a radius twice that of the Sun and is 8.6 light-years away.

Canopus and the next fixed star α Centauri, 4.2 light-years away, are also located in the Southern Sky, having declinations around −60°; too close to the south celestial pole for either to be visible from Central Europe.
