Using the European Southern Observatory's Very Large Telescope (ESO's VLT), a team of astronomers have obtained the sharpest and most detailed images yet of the asteroid Kleopatra.

The observations have allowed the team to constrain the 3D shape and mass of this peculiar asteroid, which resembles a dog bone, to a higher accuracy than ever before.

Their research provides clues as to how this asteroid and the two moons that orbit it formed.

These eleven images are of the asteroid Kleopatra, viewed at different angles as it rotates. The images were taken at different times between 2017 and 2019 with the Spectro-Polarimetric High-contrast Exoplanet REsearch (SPHERE) instrument on ESO’s VLT.

Kleopatra orbits the Sun in the Asteroid Belt between Mars and Jupiter.

Astronomers have called it a “dog-bone asteroid” ever since radar observations around 20 years ago revealed it has two lobes connected by a thick “neck”.

Location of Kleopatra in the Solar System

This animation shows where the orbit of the asteroid Kleopatra (in red) is in our Solar System.

Kleopatra orbits the Sun in the Asteroid Belt, which is located between the orbits of Mars and Jupiter.
