Earlier, on the basis on the combined data from satellite and ground-based observations, we have calculated the radiant, velocity, orbital elements, heights of the beginning, peak, and end of the trail, stellar magnitude (- 20.3(m)), and the values of deceleration at several points of the trail. However, the photometric mass and density of the superbolide have not been studied. Using the results of the combined data of satellite and ground-based observations of the Tajikistan superbolide (July 23, 2008), the mass was calculated by three methods: a) photometric, based on the light intensity at the height of maximum brightness, b) graphics (on the basis of published data of cars), c) using the kinetic energy of the superbolide. The calculated values of the mass superbolide are respectively 25.3 tone, tone and tone 19.9, 18.9. The average value of the mass, which we calculated on the three methods, it is 21.3 +/- 2.1 tons. The superbolid density was evaluated on: a) drag equation, b), equation density of atmosphere at the heights of the maximum and beginning train and c) criterion-PE. The density is calculated by the three methods is equal to 1.1 g/cm(3), 0.53 g/cm(3), and 0.95 g/cm(3).The average superbolide density is calculated by the three methods is 0.86 +/- 0.15 g/cm(3).
