Astronomers have been able to build a 3D model of Kleopatra and its two moons from two years' of observations collected by the Very Large Telescope (VLT).

"This had to be resolved. Because if the moons' orbits were wrong, everything was wrong, including the mass of Kleopatra." From here the astronomers could also work out the density of Kleopatra, finding the asteroid is less than half as dense as iron—also lower than previously believed. "Our ultimate goal is to understand all big asteroids in the main belt, including their volume, mass, density, porosity, shape, as well as structure. We are not there yet," Brož said."Generally, we think that about half of big asteroids are primordial, they have been accreted approximately 4.567 billion years ago. Another half were hit, colliding with another asteroid later on.
