A Near-Earth Object (NEO), the asteroid is called 163348 (2002 NN4) and is classified as a Potentially Hazardous Asteroid (PHA).
What are Near Earth Objects?
NASA defines NEOs as comets and asteroids nudged by the gravitational attraction of nearby planets into orbits which allows them to enter the Earth’s neighbourhood.
These objects are composed mostly of water ice with embedded dust particles.
NEOs occasionally approach close to the Earth as they orbit the Sun.
