(35396) 1997 XF11
(35396) 1997 XF11 (also written (35396) 1997 XF11) is a near-Earth and Mars-crosser asteroid which, shortly after its discovery on December 6, 1997, by James V. Scotti of the University of Arizona's Spacewatch Project, was predicted to make an exceptionally close approach to Earth in October 2028. Additional precovery observations of the asteroid were quickly found that refined the orbit and it is now known the asteroid will pass the Earth on October 26, 2028, at a distance of 0.0062 AU (930,000 km; 580,000 mi), about 2.4 times the Earth-Moon distance.[1][2] During the close approach, the asteroid should peak at about apparent magnitude 8.2,[3] and will be visible in binoculars.
(35396) 1997 XF11 is estimated to be between 1.3 km and 2.8 km in diameter.[4]
This asteroid also comes near the large asteroid Pallas.[2]
