The celestial sphere is divided into which: 88 different areas that identify, name, and plot the celestial objects 44 different areas that identify, name, and plot the celestial objects 22 different areas that identify, name, and plot the celestial objects constellations, such as orion, rigel, and sirius

Of the 88 recognized constellations by the IAU (International Astronomical Union), 36 are witnessed exclusively on the northern sky, and the left 52 are situated in the southern sky.  

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
