The polar axis, gross shape and rough surface albedo distribution of the asteroid 4 Vesta have been recently determined by two distinct and independent sets of observational data, provided by lightcurve photometry and by speckle interferometry. The results are consistent, and show that Vesta is a spheroidal or a quasi-spheroidal object whose surface has a significant albedo variegation. This is the first time that different earth-based techniques have led to a rough 'map' of an asteroidal object.

Abstract
The polar axis, gross shape and rough surface albedo distribution of the asteroid 4 Vesta have been recently determined by two distinct and independent sets of observational data, provided by lightcurve photometry and by speckle interferometry. The results are consistent, and show that Vesta is a spheroidal or a quasi-spheroidal object whose surface has a significant albedo variegation. This is the first time that different earth-based techniques have led to a rough 'map' of an asteroidal object.File in questo prodotto:
