小行星35396（天文学临时编号1997 XF11）是一颗公里大小的小行星，被归类为近地天体、火星轨道穿越小行星和阿波罗型小行星的潜在威胁天体^[1]。

性质

亚利桑那大学太空监视的詹姆斯·V·斯科蒂（James V. Scotti）于1997年12月6日发现这颗小行星。三个月后，预计该小行星将于2028年10月28日异常接近地球，距离929,000公里^[3]^[13]^[14]。在接近地球期间，小行星的峰值应约为视星等8.2等^[15]，并且在双筒望远镜中可见^[16]。

小行星35396直径介于0.7至1.4公里之间^[8]^[10]^[9]。这颗小行星也经常靠近大型小行星智神星^[14]。
