2005 YU55 will pass 0.00217 AU (325,000 km; 202,000 mi) from the Earth on 8 November 2011.

But (153814) 2001 WN5 will also pass 0.00166 AU (248,000 km; 154,000 mi) from the Earth on June 26, 2028.

Can we make a GIF animation of the WN5 Earth and moon passage in 2028?

It has a fairly well determined orbit: http://ssd.jpl.nasa.gov/sbdb.cgi?sstr=2001WN5

Here's some still images.  Animations take more time, so let me know your priorities.

If you're up to writing a new Wikipedia article, here's something as new as yesterday.  Asteroid 2011 SC191 is a newly-discovered Mars Trojan asteroid.  Now Mars has 5 of them.  Your reference is the MPML.  The other 4 have their own Wikipedia pages.  http://en.wikipedia.org/wiki/List_of_Mars_Trojan_asteroids (The caption for the image in this article is misleading since Jupiter and its trojans dominate the image, rather than Mars).  . Here's an animation I've made of the 5 known Mars trojans.  The new one is the green one.  I'm going to make some more animations of these amazing objects in the coming days.

Hi Tony ,
nice animation of the new trojan !
Did you incorporate a view from feature here ?

Yes, there's a 'view from' feature in the latest beta version (which I call Alpha 3.0).  But to make that animation, I had to tinker with the code.  I havent' yet made a GUI so the end user can change any of the 'view from' default settings.  In this image, the camera orbits the Sun from a distance of 4 AU, but with the period of Mars.  Unlike other 'view from' features that I've seen, the camera isn't simply locked at a certain distance behind Mars, along the Mars-Sun line.  Otherwise Mars would simply be a point in front of the Sun.  Rather, the camera orbits the Sun at a constant speed.  I also elevated it above the ecliptic so it doesn't give the impression that the loop caused by Mars is Mars' orbit around the Sun.  Rather it is Mars orbiting around its average position.
