Thanks to the Very Large Telescope of the European Southern Observatory (ESO's VLT) and with the help of TRAPPIST telescopes, a team of astronomers including researchers from ULiege acquired the sharpest and most detailed images at this day of the triple asteroid Kleopatra. These observations made it possible to constrain the three-dimensional shape as well as the mass of this particular asteroid, similar to a dog bone. In addition, this work provides a better understanding of the formation of this asteroid as well as of the two moons that orbit around it.
