- 1994 WR12 is an asteroid and near-Earth object approximately 130 meters (430 feet) in diameter. As a member of the Aten group almost all of its orbit is closer to the Sun than Earth is. On 24 November 1994 it passed about 374100 km from the Moon. First imaged at Kitami Observatory on 26 November 1994, it was discovered two nights later by American astronomer Carolyn S. Shoemaker at Palomar Observatory on 28 November 1994. The asteroid then went unobserved from 1994 until it was recovered by Mauna Kea in March 2016. It was removed from the Sentry Risk Table on 2 April 2016. (en)

- 1994 WR12（也可以寫成1994 WR12）是一顆軌道尚不明確的近地小行星。在1994年11月26日首度獲得它的影像，並且在1994年11月28日被帕洛馬山天文台（675）的卡羅琳·舒梅克發現。它的直徑大約130公尺，並且被列入哨兵監測表。由於軌道不確定，下一次可能要到2044年才能仔細觀察這顆小行星，屆時它可能以0.03–0.19 au的距離掠過地球。 用已知的軌跡但不確定軌道仿真模擬顯示，在2054－2113年會有125次撞擊的威脅，這等同於10000次中有1次撞擊地球的機會。對這顆小行星已知軌跡的缺乏（不確定性=8），會因為接近金星和水星變得更複雜。 估計它的撞擊可以產生77百萬噸TNT的能量，大約是有史以來最強大的沙皇炸彈的1.5倍。 (zh)
