\n\tWe have derived Earth Similarity Index (ESI) with two free parameters m and T, where m denotes the weight exponent and T denotes the threshold value. These free parameters are optimized with the consideration that the planet Mars is almost similar to the Earth. For the optimized values of free parameters, the interior-ESI, surface-ESI and ESI for some planets are calculated. The results for m= 0.8 and T= 0.8 are compared with the values obtained. We have found that the exoplanet 55 Cnc f is within 10% away from the threshold value T. The exoplanets HD 69830 c, 55 Cnc c, 55 Cnc f, 61 Vir d and HIP 57050 b are found to have ESI within 10% from the threshold value.
