Statistical survey and analysis of photometric and spectroscopic data on NEAS

Studies on Near Earth Asteroids (NEAs) throw light on discoveries, identification, orbit prediction and civil alert capabilities, including potential asteroid impact hazards. Due to various new observational programs, the discovery rate of NEAs has drastically increased over the last few years. In this paper we present the statistical survey and analysis of fundamental parameters (derived from Photometric and Spectroscopic observations) of a large sample of NEAs from various databases like IAU Minor Planet Center, European Asteroid Research Node (E.A.R.N.), Near Earth Objects - Dynamic Site (NEODyS- 2), M4AST and SMASSMTT portals. We also discuss the characterization of NEAs on the basis of the correlations between theparametersstudied from different observationsand theirphysical implicationsin understanding the nature and physical properties of these objects.
