小惑星の観測記録  下のリストは,2008年6月までに報告・公表された年度別の小惑星観測数である. 毎年の小惑星の観測数は,1990年以前には,数万個,1990年代初期は,およそ,10万 個足らずであった.しかし,1998年頃に開始されたLINEARサーベイによる小惑星捜索 の結果,1998年には,1年間の観測数は 100万個を越えた.さらに,各地で小惑星サ ーベイが行なわれるようになり,最近では,その年間の報告数は,700万個を越えてい る.  一方,我が国アマチュアによる観測数は,1992年には世界の9%を占めた.また,世 界の 19%となる新小惑星の発見も報告された.彼らによる観測・発見数は,1997年に もっとも多くなったが,以後,全天サーベイの成果にやる気をなくしたのか,以後, 急速に衰退していった. なお,現在までに,報告されている小惑星の総観測数は,5542万個余,新たに発見 されて仮符号が与えられた小惑星の総数は,77万個余である.
