Flattening ratio a/c of the Maclaurin spheroid as a function of angle θ between the spheroid’s rotation axis and the line of sight. Without a density estimate, true flattening ratios up to the bifurcation point are theoretically plausible. We argue that a more realistic lower density limit is ρ = 0.73 g cm^-3, which would exclude extreme axis ratios and therefore constrain the volume of the body considerably.
