A set of equations are derived which describe the separation between the original\nand deflected orbits and the equations are integrated from perihelion where a velocity change is\ngiven in the direction of the orbital motion. For a predicted collision to be avoided, the\nseparation ought to be greater than the Earth radius at the time when the asteroid crosses the\nEarth' orbit. It is found that if the lead time from perihelion is denoted by t measured in years,\nthe required velocity change is 0.22(t/10)-1 cm/sec for a (semi-major axis) =2 AU and\n0.17(t/10)-1 cm/sec for a=3 AU for eccentricities greater than 0.7. These values are somewhat\nless than the estimates obtained in earlier investigations.","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"奈良産業大学情報学部"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藪下, 信"},{"creatorName":"ヤブシタ, シン","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Komori, Seiji"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yabushita, Shin","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Komori, Seiji","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-08-26"}],"displaytype":"detail","filename":"yabushita2002b.pdf","filesize":[{"value":"203.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"本文PDF","url":"https://naragakuen.repo.nii.ac.jp/record/484/files/yabushita2002b.pdf"},"version_id":"9e7ce04c-e58a-4d92-8e1e-7840c7f309e3"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"asteroids-collision with earth-orbit deflection.","subitem_subject_scheme":"Other"},{"subitem_subject":"asteroids-collision with earth-orbit deflection.","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"On the Deflection of the Orbits of Earth Colliding Asteroids","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"On the Deflection of the Orbits of Earth Colliding Asteroids"},{"subitem_title":"On the Deflection of the Orbits of Earth Colliding Asteroids","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"10","path":["137"],"pubdate":{"attribute_name":"公開日","attribute_value":"2016-08-26"},"publish_date":"2016-08-26","publish_status":"0","recid":"484","relation_version_is_last":true,"title":["On the Deflection of the Orbits of Earth Colliding Asteroids"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2023-06-20T14:59:17.885340+00:00"}
