It was discovered on 5 October 2002, by the LINEAR project at Lincoln Laboratory's ETS in Socorro, New Mexico. It was announced on 7 October 2002 and appeared later that day on the JPL current risk page.
(163364) 2002 OD20 is an asteroid, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, likely smaller than one kilometer in diameter.
(529366) 2009 WM1, provisional designation 2009 WM1, is a sub-kilometer asteroid and near-Earth object of the Apollo group, approximately 280 meters (920 feet) in diameter.

2014 XL7 is a near-Earth object and Apollo asteroid, approximately 230 meters (750 feet) in diameter. It was the most dangerous potentially hazardous asteroid on Sentry Risk Table upon its discovery by the Mount Lemmon Survey in December 2014. At the time, the asteroid had a cumulative 1 in 83000 chance of impacting Earth on 4–5 June between the years 2048 and 2084. After the object's observation arc had been extended to 35 days, it was removed from the Sentry Risk Table on 15 January 2015. Since then the asteroid's orbit has been secured. Although it has an Earth minimum orbit intersection distance of less than one lunar distance, there are no projected close encounters with Earth in the foreseeable future, with its closest passage to occur in May 2046, still millions of kilometers away.
