'''3122 Florence''' (1981 ET3) adalah sebuah [[asteroid]]. Asteroid ini merupakan bagian dari [[asteroid Amor]], yang terletak dekat dengan [[bumi]]. [[Eksentrisitas orbit]] asteroid ini tercatat sebesar 0.423, sementara [[magnitudo mutlak]]nya adalah 14.1.
 
'''3122 Florence''', atau dikenal juga sebagai 1981 ET<sub>3</sub>, merupakan sebuah [[asteroid]] yang masuk dalam grup [[Amor asteroid|Amor]]. Diklasifikasikan sebagai asteroid dekat [[bumi]] yang berpotensi membayakan, [[asteroid]] ini memiliki diameter sekitar 4,3 hingga 5 kilometer. [[Asteroid]] raksasa ini ditemukan pada 2 Maret 1981 oleh astronom Amerika Serikat [[Schelte Bus]] di Observatorium Siding Spring.<ref name="MPC-Florence" />
== Pembentukan ==
 
''Florence'' mengorbit [[Matahari]] pada jarak sekitar 1,0–2,5&nbsp;[[Satuan astronomi|AU]] sekali setiap 2 tahun 4 bulan (859 hari). [[Asteroid]] ini memiliki [[eksentrisitas orbit]] sekitar 0,42 dan [[inklinasi]] sekitar 22[[Degree (angle)|°]] terhadap bidang [[ekliptika]].<ref name="jpldata" />
Seperti asteroid secara keseluruhan, asteroid ini terbentuk dari [[nebula]] [[matahari]] primordial sebagai pecahan [[planetisimal]], sesuatu di nebula matahari muda yang tidak cukup besar untuk berubah menjadi [[planet]].<ref>{{cite web | title=What Are Asteroids And Comets? | url=http://neo.jpl.nasa.gov/faq/#ast | work=Near Earth Object Program FAQ |publisher=[[NASA]] | accessdate=13 September 2010 | archiveurl=http://web.archive.org/web/20100909210213/http://neo.jpl.nasa.gov/faq/| archivedate=9 September 2010 | deadurl=no}}</ref>
 
Pada 1 September 2017, asteroid ini akan mencapai jarak {{convert|0,04723|AU|km mil|lk=on|abbr=on}} dari Bumi,<ref name="jpl-close" /> ia akan tampak dengan [[Magnitudo semu|magnitudo visual]] +8,5, sehingga dapat terlihat melalui [[teleskop]] kecil untuk beberapa malam ketika ia bergerak dari konstelasi [[Piscis Austrinus]], [[Kaprikornus]], [[Akuarius]] dan [[Delphinus]].<ref>{{cite news|title=Nasa says big asteroid to pass safely by Earth on 1 September|url=http://www.livemint.com/Science/0Far3fmQLS4Bq6kUXKrMjM/Nasa-says-big-asteroid-to-pass-safely-by-Earth-on-1-Septembe.html|agency=Livemint}}</ref>
 
Penamaan ilmiah untuk [[asteroid]] ini telah dipublikasikan pada 6 April 1993 ({{small|[[Minor Planet Circulars|M.P.C.]] 21955}}).<ref name="MPC-Circulars-Archive" />
