Template:Downsize (35396) 1997 XF11 (also written (35396) 1997 XF11) is a near-Earth and Mars-crosser asteroid which, shortly after its discovery in December 1997, was predicted to make an exceptionally close approach to Earth in October 2028. Additional prediscovery observations of the asteroid were quickly found and the present orbit will take the asteroid past the Earth on October 26, 2028 at the relatively safe distance of 930,000 kilometers (580,000 miles), about 2.4 times the Earth-Moon distance.[1][2]
What makes (35396) 1997 XF11 special is that it is estimated to be between 1.3km and 2.8km in diameter.[3]
This asteroid also comes near Pallas.[2]
The asteroid was discovered on December 6, 1997 by James V. Scotti of the University of Arizona's Spacewatch Project.
(35396) 1997 XF11 in fiction
This asteroid is similar to one in the audio play "Spock vs. Q". An asteroid (the size of Montana)[4] was to have collided with Earth in 2000, but Q diverts it until the year 2028 since Spock was able to convince him that humans were worth saving (and Spock beats Q in a logic competition)[citation needed].
