Spock vs. Q reference

"According to the audio play "Spock vs. Q,"....[citation needed] THE CITATION IS IN THE SENTENCE YOU FOOLS [--138.251.229.70, November 21, 2007]

• I listened to Spock vs. Q and heard no indication that the asteroid there was specifically this one. --Lkseitz (talk) 05:14, 28 November 2007 (UTC)

How big is it?

How large in diameter/radius is this asteroid? —Preceding unsigned comment added by 172.166.46.23 (talk) 19:05, 2 January 2008 (UTC)

1997

How fake are the previsions? I remember that the discovery of XF11 was very frightening because it was discovered after it had passed between Earth and Moon. This fact is not told anymore and in Nasa simulations software the calculate distance of passage of this object in 1997 is very far from the moon. So what is happening with Nasa simulation tool? — Preceding unsigned comment added by 187.105.200.230 (talk) 01:37, 8 February 2012 (UTC)

On 1997-May-08 the asteroid passed 0.1555 AU (23,260,000 km; 14,450,000 mi) from the Earth. At the time of discovery in December 1997, the original observation arc of only a few days could have show a best-fit prediction of a closer passage in May 1997, but you can not make a highly accurate prediction 7 months into the past based on an observation arc of only a couple of days. As the observation arc gets larger you can more accurately predict past and future close-approaches. I have added a section about the incorrect March 1998 claims about the asteroid passing inside the orbit of the moon in 2028. -- Kheider (talk) 02:07, 8 February 2012 (UTC)

Pallas close approach claims

The article claims that this asteroid comes close to asteroid Pallas. I don't think that's true. The MOID is about 0.28 AU (42.5 million km), not closer than many other Near Earth asteroids with sufficiently large aphelion distance. The source given does not lead anywhere, but the current NeoDyS and JPL close approach predictions do not list any close approaches to Pallas in the next century.
