It never ceases to amaze me that despite 4.6 billion years of accretion, there are still a prodigious number of pieces of junk out there. Inevitable I suppose that the on-going sky surveys will pick up a frighteningly large rock heading our way - just a question of when..

Close approach in about 5 minutes! Here's an animation I made that shows the encounter from the asteroid's point of view: http://www.youtube.com/watch?v=AkBFNOah4q0 Itokawa standing in for 2011 MD, and a WAG for the rotation state. --Chris |

NASA To Host News Conference On Asteroid Search Findings WASHINGTON -- NASA will hold a news conference at 1 p.m. EDT on Thurs., Sept. 29, to reveal near-Earth asteroid findings and implications for future research. The briefing will take place in the NASA Headquarters James E. Webb Auditorium, located at 300 E St. SW in Washington.
NASA's Wide-field Infrared Survey Explorer (WISE) mission, launched in December 2009, captured millions of images of galaxies and objects in space. During the news conference, panelists will discuss results from an enhancement of WISE called Near-Earth Object WISE (NEOWISE) that hunted for asteroids. The panelists are: -- Lindley Johnson, NEO program executive, NASA Headquarters, Washington -- Amy Mainzer, NEOWISE principal investigator, NASA's Jet Propulsion Laboratory, Pasadena, Calif. -- Tim Spahr, director, Minor Planet Center, Smithsonian Astrophysical Observatory, Cambridge, Mass. -- Lucy McFadden, scientist, NASA's Goddard Space Flight Center, Greenbelt, Md. The event will air live on NASA Television and the agency's website. For NASA TV streaming video, downlink and scheduling information, visit: http://www.nasa.gov/ntv The briefing also will be streamed live, with a chat available, at: http://www.ustream.tv/nasajpl2 For more information about the mission, visit: http://www.nasa.gov/wise |

a near miss in 1883?
Interpretation of the observations made in 1883 in Zacatecas (Mexico): A fragmented Comet that nearly hits the Earth I tend to be skeptical of this kind of old visual obs, but well, who knows... |

the paper is making some buzz on the internet: Was the “First Photographed UFO” a Comet?
