Comparable in size to the Golden Gate Bridge (0.74 km diameter)
163348 (2002 NN4) is a small asteroid whose orbit could bring it in close proximity to Earth. NASA JPL has classified 2002 NN4 as a "Potentially Hazardous Asteroid" due to its predicted close pass(es) with Earth.
2002 NN4 orbits the sun every 299 days (0.82 years), coming as close as 0.50 AU and reaching as far as 1.26 AU from the sun. 2002 NN4 is about 0.7 kilometers in diameter, making it larger than ~97% of asteroids but small compared to large asteroids, comparable in size to the Golden Gate Bridge.
The rotation of 2002 NN4 has been observed. It completes a rotation on its axis every 14.50 hours.
2002 NN4's orbit is 0.01 AU from Earth's orbit at its closest point. This means that its orbit is relatively close to Earth's orbit.
