Results of the investigation of the asteroid (2121) Sevastopol based on photometric observations of mutual phenomena

摘要

The asteroid (2121) Sevastopol is a binary asteroid from the main belt. The duplicity of the asteroid was discovered based on photometric observations of mutual phenomena (eclipses and occultations) that were detected in its light curves (Higgins et al., 2010).We organized a photometrical observational campaign for the observations of mutual phenomena in binary system of the asteroid (2121) Sevastopol and an investigation of the properties of the asteroids satellite. The observations allowed us to define mass, density, taxonomical class and preliminary orbit of the satellite of the asteroid (2121) Sevastopol.
