Therefore we studied the orbital evolution of Itokawa by a statistical method and found that the fate of Itokawa is most likely to collide with the sun or inner planets. The probability of collision with the earth is about once in one million years. As for the past of Itokawa, it is most likely that the origin of Itokawa is near the inner edge of the asteroid belt. This orbital evolution of Itokawa is typical for the near-Earth objects, so the investigation of Itokawa is important not only from the scientific point of view but also from the point of spaceguard.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063350038","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部"},{"subitem_text_value":"Observatoire de la Cote d'Azur"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Observatoire de la Cote d'Azur"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉川, 真"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Michel, Patrick"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshikawa, Makoto","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Michel, Patrick","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"イトカワ","subitem_subject_scheme":"Other"},{"subitem_subject":"小惑星","subitem_subject_scheme":"Other"},{"subitem_subject":"軌道進化","subitem_subject_scheme":"Other"},{"subitem_subject":"軌道計算","subitem_subject_scheme":"Other"},{"subitem_subject":"惑星軌道","subitem_subject_scheme":"Other"},{"subitem_subject":"小惑星衝突","subitem_subject_scheme":"Other"},{"subitem_subject":"小惑星帯","subitem_subject_scheme":"Other"},{"subitem_subject":"誤差","subitem_subject_scheme":"Other"},{"subitem_subject":"地球近傍天体","subitem_subject_scheme":"Other"},{"subitem_subject":"はやぶさ","subitem_subject_scheme":"Other"},{"subitem_subject":"MUSES-C","subitem_subject_scheme":"Other"},{"subitem_subject":"小惑星探査機","subitem_subject_scheme":"Other"},{"subitem_subject":"Itokawa","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asteroid","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"orbital evolution","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"orbit calculation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"planetary orbit","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asteroid collision","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"asteroid belt","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"error","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"near Earth object","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hayabusa","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"MUSES-C","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Asteroid Sample-return Spacecraft","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"Orbital evolution of asteroid (25143) Itokawa","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Orbital evolution of asteroid (25143) Itokawa","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["1791","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"20553","relation_version_is_last":true,"title":["Orbital evolution of asteroid (25143) Itokawa"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:48:38.881031+00:00"}
