Abstract

In this work, the quantification of Near-Earth Object (NEO) has been carried out between 1990 to 2021. The emphasis is to examine the total number NEO discovered, the relationship between them and the earth-orbit especially with respect to their magnitude and distance (objects, aphelion and perihelion). Three categories of data (Amors, Apollos and Atens) were sourced from Minor Planet Center data repository (minorplanetcenter.net//iau/lists/Unusual.html), based on their orbital revolution and the pattern. Exploratory data analysis (EDA) of 5700 NEOs samples using python analytics was carried out and the result shows the average distribution of minimum distance between earth-orbit and NEOs. The result also shows yearly distribution of mean distance and magnitude. Furthermore, out of the 5700 NEOs analyzed, 22.9% were found to be potentially hazardous asteroids (PHAs) with higher possibility of an encounter with the earth, found at 0.01AU distance from the earth-orbit.
