Hypergiant Mass-Radius Correlation

[vh]

So i wikipedia'd and searched up every "hypergiant" star i could find..which was like 16, 3 of which are very vague.

I have them on the attached excel, and it seems to have no pattern. maybe try plugging it in to a linear or quadratic etc regression calc and see what comes up...

pasted the data here but it's horrible formatted.

Mass (Solar masses)   Radius (Solar Radius)   Star
30   76   P Cygni
45   240   S Doradus
125   140   Eta Carinae
115   320   Pistol Star
115   150   LBV 1806-20
60   52   Zeta1 Scorpii
92   244   Cygnus OB2-12
265   35   R136a1
25   170   6 Cassiopeiae
40   450   Rho Cassiopeiae
25   400   V509 Cassiopeiae
39   747   V382 Carinae
40   1500   RW Cephei
9   1016   VX Sagittari

VY Canis Majoris is a biggun'

but very, very light  
in fact, VY Canis Majoris, on average, is 1/1000th of a percent the density of air!
A Sun sized object the density of VY Canis Majoris would weigh as much as 5% of the earths mass, an object a million times smaller.
