Amsterdam, Feb 5 : A team of French and Italian astronomers has devised a new method for measuring the size and shape of asteroids, which would increase the number of asteroids that can be measured by a factor of several hundred.
This method takes advantage of the unique capabilities of ESO's Very Large Telescope Interferometer (VLTI).
"Knowledge of the sizes and shapes of asteroids is crucial to understanding how, in the early days of our Solar System, dust and pebbles collected together to form larger bodies and how collisions and re-accumulation have since modified them," said Marco Delbo from the Observatoire de la Cote d'Azur, France, who led the study.
