We have conducted a detailed analysis of the dust structure around PSR J0856-6137 in the far infrared band by using Sky View Virtual observatory in two surveys: IRIS (60 μ m and 100μ m) and AKARI (90μm  and 140μm) survey. We have studied different physical properties such as dust color temperature, dust mass, and Planck’s function. The maximum and minimum temperature was found to be 24.815 ± 0.008K, 23.899 ± 0.008K and 27.759 ± 0.016K, 26.178 ± 0.016K in the IRIS and the AKARI surveys respectively. In both cases, the offset temperature was obtained less than 2 k. The average dust mass was found to be 1.341×1027 kg and 1.460 ×1025 kg in the IRIS and the AKARI surveys respectively. We found a small offset temperature, which suggests that the system is in a state of thermal equilibrium. We conducted a comparison of these physical parameters and found similar results to those of earlier research. This research can aid in comprehending the evolution of the pulsar.
