Optical observation is one of the most common techniques used for characterizing the physical properties of unknown objects\udand debris in space. This research presents measurements and properties of the new object 96019 from ground-based optical\udmethods. Optical observations of this small object were performed using a charge-coupled device (CCD) camera and the\udSantel-500 telescope at the Zvenigorod Observatory. The orbital elements and physical properties of this object, such as areato-\udmass ratio, have been determined. The results show that this small object has a low area-to-mass ratio, between 0.009 and\ud0.12 m2/kg. The light curve of object 96019 is given: Over the time intervals, variations in brightness are analyzed and the\udmaximum brightness was found to be 12.4 magnitudes. The observational results show that, this object brightens by about\udthree magnitudes over a time span of three minutes. Based on these observations, the characteristics and physical properties\udof this object are discussed
