番号登録小惑星の登録リスト　2008年６月末までに番号登録された小惑星の各天文台コード別，発見リストを以下に示す．　これまでに番号登録された小惑星は，18万9005個．これらの小惑星は，世界各地の 398ヶ所の天文台で発見された．その登録数がもっとも多いのは，LINEARサーベイの９万6032個．つまり，番号登録小惑星の半分以上は，LINEARサーベイの発見によるもので，今後もこの傾向は，当分，続くだろう．続いて，キットピークの１万 6387個（ほとんどがスペースウォッチ・サーベイによるもの），パロマー（多くが NEATサーベイ）の１万1786個，ローエルの１万1639個（多くがLONEOSサーベイ），パロマー山の6435個（かなりの数のパロマー・ライデン天体(PL, T1, T2. T3)を含む）となる．　続いて，最近では，小惑星の発見がほとんどなくなった我が国アマチュア（表の＊）によって発見された小惑星の中で，番号登録された小惑星が，総数で6087個と続く．この数には，専門機関（表の＋）の登録数は含まれていない．これは，番号登録小惑星全体の 3.22%を占める．なお，我が国でのこれらの番号登録小惑星の発見は，53ヶ所の天文台で行なわれた．番号登録小惑星を発見した我が国内の天文台数は，天文台全体の13.3%を占める．　我が国でもっとも登録数の多いのは，群馬の小林隆雄氏で2425個（大泉2422個＋黒保根3個）で，氏は世界順位の第９位にいる．国内第２位は，釧路（上田＋金田）の723個，第３位が北見（円館＋渡辺）の658個で，それぞれ，世界順位の20位と22 位である．なお，これらの発見者の中で，北見の円館金氏以外は，現在，小惑星の捜索を行なっていない．　番号登録小惑星の中で，ｑ＜1.3 AUより小さい小惑星（NEO）の登録数は850個．この数は，番号登録小惑星のわずかに 0.45%を占める．つまり，確率的には，登録小惑星を 222個発見すると，１個の NEOが発見できるという確率となる．最近，多くのNEOが発見されているように思われがちであるが，特異小惑星（NEOを含む）の発見は，中々に難しい．　特に国内の専門機関では，海外のサーベイのように「天体（NEOを含む）の発見が，好きで好きでたまらない」．「飯の種より好きだ」．そのためには「毎夜でも捜索を惜しまない」という職員が行なっているわけではない．このため，国内での今後の NEOの発見は 200個に１個という発見確率以上に，さらに，困難を極めるだろう．　この NEOの登録数がもっとも多いのは，LINEARサーベイで 373個，続いて，第２位がパロマー山の 111個，第３位がキットピークの 71個となる．　我が国アマチュアによるこの種の小惑星の登録は，わずかに11個で，この数は，我が国で発見された彗星の発見数よりも少ない．もっとも多くの発見は，小林氏によるもので３個である．続いて，ダイニック（杉江）の２個，釧路，芸西（関），月光（大島），八ヶ岳（串田），仙台（小石川），静岡（鬼沢）の１個と続く．　番号登録された小惑星は，原則，その発見者が命名できる．その中ですでに命名された小惑星は，１万4296個で，全体での命名率は 7.56%となる．我が国の発見で命名された小惑星は，これまでに1390個，その命名率は22.8％となる．最近では，番号登録された小惑星への命名は，その直径が大きな小惑星（Ｈ＜16等）にしか認められない傾向にあるために，我が国で発見された小惑星の残り4697個への命名を急いで欲しい．　なお，現在，私（中野）は，IAU Division Ⅲが運営する「IAU微小天体命名委員会」の委員をしている．命名を申請して，数カ月経過しても，それが MPC誌上に公表されないときは，命名に問題があるものと思われるので，ご一報いただきたい（私の方からは，申請された命名が没になったことを連絡はしない）． (ｑ＜1.3 AU) No. ｺ-ﾄﾞ天文台名登録個数命名済未命名命名率 NEO -------------------------------------------------------------------------- 1 704 Lincoln Lab.
