Leet o constellations bi area
The buird ablo ranks the 88 modern constellations bi the solid angle that thay subtend in the lift, measured in square degrees n millisteradians.
Thir solid angles depend oan arbitrie boundaries atween the constellations: the leet ablo is based oan constellation boundaries drawn up bi Eugène Delporte in 1930 oan behalf o the IAU n publeesht in Délimitation scientifique des constellations (Cambridge Varsity Press). Afore Delporte's wairk, thaur wis nae precise leet o the boundaries o ilka constellation.
Delporte drew the boundaries alang verteecal n horizontal lines o richt ascension n declination; houever, he did sae fer the epoch B1875.0, this means that cause o the precession o the equinoxes, the borders oan ae modern stair cairt (e.g., fer epoch J2000) ar awreadie ae wee bit aff kilter n ar nae langer perfectlie vertical or horizontal. This skew will graw ower the years n centuairs tae come. Houever, this disna chynge the solid angle o onie constellation.
