Aims. We investigate the nucleus photometric properties of the comet 67P/Churyumov-
Gerasimenko as observed by the Visible and Infrared Thermal Imaging Spectrometer …

Aims. We present a study of the spectrophotometric properties of dwarf planet Ceres in the
visual-to-infrared (VIS-IR) spectral range by means of hyper-spectral images acquired by the …

The visible reflectance spectrum of many Solar System bodies changes with changing
viewing geometry for reasons not fully understood. It is often observed to redden (increasing …

NASA's Dawn mission was launched in September 2007 and orbited asteroids Vesta
(2011− 2012) and Ceres (2015–2018). Vesta shows surface dark units that have been …

At the beginning of the Ceres investigation, the Dawn-NASA mission discovered a large
bright spot (BS) in the Occator crater floor. Several other smaller bright spots were …

Asteroid photometry has three major applications: providing clues about asteroid surface
physical properties and compositions, facilitating photometric corrections, and helping …

Remote sensing data acquired during Dawn's orbital mission at Vesta showed several local
concentrations of high-albedo (bright) and low-albedo (dark) material units, in addition to …

Vesta is the asteroid with the largest albedo variation among the known rocky Solar System
objects and shows a widespread occurrence of dark material (DM) and bright material (BM) …

Thanks to the VIR spectrometer onboard NASA's Dawn spacecraft, which orbited Vesta in
2011–2012, thousands of hyperspectral images of its surface have been collected. The …

Among main belt asteroids, some have a spectrum similar to Vesta so they are
taxonomically classified as V-type asteroids. Probably they were removed from Vesta and …
