About This Dataset
Smallest Constellations by Area
This chart ranks the smallest of the 88 official constellations by area, in square degrees, as defined by the International Astronomical Union. Crux, the Southern Cross, is the smallest of all.
Analysis
The top three in Area (square degrees) are Crux (68.4), Equuleus (71.6) and Sagitta (79.9). The 10 entries in Area (square degrees) cover a range of 115, from 183.4 down to 68.4. First and second are separated by 3.20, so the leader sits inside the field rather than apart from it. The other 8 are bunched between 79.9 and 183.4 Area (square degrees).
