Stars (and constellations) that are circumpolar in one hemisphere are always invisible at the same latitude (or higher) of the opposite hemisphere, and these never rise above the horizon. For example, the southern star Acrux is invisible from most of the contiguous United States , likewise, the seven stars of the northern Big Dipper asterism ...

The constellation is located within the Milky Way, and hence has many stars. [11] A roughly equilateral triangle, it is easily identifiable. Triangulum Australe lies too far south in the celestial southern hemisphere to be visible from Europe, [10] yet is circumpolar from most of the southern hemisphere. [11]
Alpha Reticuli, Latinized from α Reticuli, is the brightest star in the southern circumpolar constellation of Reticulum, [12] with an apparent visual magnitude of 3.3. [2] This appears to be a solitary star [13] located at a distance of 160 light-years from Earth. [1]

At the equator, it is possible to see both Polaris and the Southern Cross. [16] [17] The celestial south pole is moving toward the Southern Cross, which has pointed to the south pole for the last 2000 ...
