2015 DR215 is a stony near-Earth asteroid of the Atira class residing within Earth's orbit. It was discovered on 18 February 2015 by the Pan-STARRS 1 survey at Haleakalā Observatory at Maui, Hawaiʻi.[1][2] The asteroid has a diameter of about 200 m (660 ft)[4] and makes close approaches within 0.05 AU (7.5 million km; 4.6 million mi) of Earth, making it a potentially hazardous object.[3] On 11 March 2022, it made a close approach 0.045 AU (6.7 million km; 4.2 million mi) from Earth,[3] reaching a peak apparent magnitude of 17 as it streaked across the southern sky.[1]
