648:. These observations confirmed the body's short rotation period and complex and irregular, and revealed, that it has a long-axis extent of 80–100 meters with an equatorial aspect ratio of about 2:1. Any significant non-principal axis rotation, commonly known as "tumbling" could be ruled out. The radar images also showed angular features up to approximately 30 meters across, with a cluster of radar-bright pixels following its rotation, and consistent with a high standing, 15 to 20 meters wide feature.
553:. On 7 July 2015, it passed Earth at 0.00295299 AU (442,000 km), or 1.15 lunar distances. On the following day, it passed the Moon at 0.00276 AU (413,000 km). This was the asteroid's closest approach to Earth until at least 2419.
