163348 (prov. designation: 2002 NN4) is a near earth asteroid, approximately 1 kilometer (0.62 miles) in diameter. It was discovered on 9 July 2002, by Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site.[1]

It flew by the earth on 5 June 2020, passing 5.2 million kilometers from the earth.[14]

Orbit

It orbits the Sun at a distance of 0.5–1.3 AU once every 10 months (300 days; semi-major axis of 0.88 AU). Its orbit has an eccentricity of 0.43 and an inclination of 5° with respect to the ecliptic.[3]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, measures between 0.735 and 19.78 kilometers in diameter and its surface has an albedo between 0.030 and 0.0839.[4][5][6][7][8][9][10][11][12]

The Collaborative Asteroid Lightcurve Link an albedo of and a diameter of kilometers based on an absolute magnitude of 12.7.[2]
