(5496) 1973 NA is an Apollo-type near-Earth minor planet. It was discovered by Eleanor F. Helin at the Palomar Observatory in San Diego County, California, on July 4, 1973. This was two days after the asteroid had passed 0.07984 AU (11,944,000 km; 7,422,000 mi) from Earth. It was tracked for more than a month, but was not seen again until 1992 when it was recovered as 1992 OA by Siding Spring Observatory. It is one of the first near-Earth asteroids ever discovered. The asteroid is roughly 3 km in diameter.
5496 (1973 NA) is expected to be related to the Quadrantids January meteor shower.
