Description:
The locations of the pole and rotation axis of asteroid 25143 Itokawa were derived from Asteroid Multiband Imaging Camera data on the Hayabusa spacecraft. The retrograde pole orientation had a right ascension of 90.53 degrees and a declination of -66.30 degrees (52000 equinox) or equivalently 128.5 degrees and -89.66 degrees in ecliptic coordinates with a 3.9 degrees margin of error. The surface area is 0.393 square kilometers, the volume is 0.018378 cubic kilometers with a 5% margin of error, and the three axis lengths are 535 meters by 294 meters by 209 meters. The global Itokawa revealed a boomerang-shaped appearance composed of two distinct parts with partly faceted regions and a constricted ring structure.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Demura, Hirohide -- Kobayashi, Shingo -- Nemoto, Etsuko -- Matsumoto, Naoya -- Furuya, Motohiro -- Yukishita, Akira -- Muranaka, Noboru -- Morita, Hideo -- Shirakawa, Ken -- Maruya, Makoto -- Ohyama, Hiroshi -- Uo, Masashi -- Kubota, Takashi -- Hashimoto, Tatsuaki -- Kawaguchi, Jun'ichiro -- Fujiwara, Akira -- Saito, Jun -- Sasaki, Sho -- Miyamoto, Hideaki -- Hirata, Naru -- New York, N.Y. -- Science. 2006 Jun 2;312(5778):1347-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Computer Software, University of Aizu, Ikki-machi, Aizu-Wakamatsu City, Fukushima 965-8580, Japan.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16741112" target="_blank"〉PubMed〈/a〉
