The probability of this being true is so close to zero it's not even fun. There's absolutely no reason to assume that the density of 33 Polyhymnia is actually 75 g/cm3.
"However, given Polyhymnia's diameter of 54 km (34 mi), this mass implies an extremely high density of 75.28±9.71 g/cm3. Such a high density is unphysical, so this mass and density estimate of Polyhymnia is considered unreliable by Carry in his study. Because of Polyhymnia's small size, its gravitational influence on other bodies is extremely difficult to detect and may lead to highly inaccurate mass and density estimates. No other study has attempted to determine a mass and density for Polyhymnia since." (https://en.wikipedia.org/wiki/33_Polyhymnia https://en.wikipedia.org/wiki/33_Polyhymnia)
