NEO is considered to have trajectory 0.3au of earth’s orbit. These objects impact on the moon, the earth and on other planets have left the craters. Impacts are one of the most fundamental processes shaping planetary surfaces throughout the solar system. A study of NEO between 1917 to 2017 is carried out by taking the parameters like nearest distance of approach with nominal and minimum values, diameter, absolute magnitudes, relative velocities and diurnal variations. The study helps to develop an Earth impact numerical model and also helps us to understanding the gravitational perturbation of planets and NEO’s impact threat. In this paper a brief analysis of variations in parameters of NEO during 1917-2017 is given (data from https://cneos.jpl.nasa.gov) based on closest approach and magnitude, potentially Hazardous NEO’s study is also presented.
