Density
In the year 2000, Merline estimated Pulcova to have a density of 1.8 g/cm³, which would make it more dense than the binary asteroids 45 Eugenia and 90 Antiope. But estimates by Marchis in 2008 suggest a density of only 0.90 g/cm³, suggesting it may be a loosely-packed rubble pile, not a monolithic object.
