Binary asteroids are continuously being discovered in the main belt. Characterization of these system are very important to understand and constrain the origin and evolution of our Solar System. Physical and orbital parameters can be obtained from the analysis of the light curves during mutual events (e.g. [1]).The binary nature of asteroid 2121 Sevastopol was discovered in 2010 by D. Higgins et al. Observation: New photometric observations of mutual phenomena (eclipses and occultations) in the binary asteroid 2121 Sevastopol have been carried out. The observations have been performed from June till November, 2016 using professional and amateur observatories placed in Argentina, France, Italy, New Zeeland and Russia.Method: New simulations of this binary asteroid have been made based on these photometric data. Thus we can be able to improve the knowledge of this system and discover their physical and orbital parameters, such as orbital elements, masses and density of the components.
