Meskipun menggambarkan Pavo pada petanya, Bayer tidak memberi penomoran bintang-bintangnya menurut [[:en:Bayer designation|designasi Bayer]]. Penjelajah dan astronom Prancis [[Nicolas Louis de Lacaille]] memberi label pada bintang-bintang itu "Alpha" sampai "Omega" pada tahun 1756, tetapi tidak menyebut "Psi" dan "Xi", serta memberi label dua pasang bintang yang terletak berdekatan Mu dan Phi Pavonis. Pada tahun 1879, astronom Amerika [[:En:Benjamin Apthorp Gould|Benjamin Gould]] memberi label bintang Xi Pavonis karena ia merasa tingkat kecerahannya mengizinkan penamaan, tetapi menggugurkan penamaan Chi Pavonis karena pudar.<ref name="wagman">{{cite book|last = Wagman|first = Morton|date = 2003|title = Lost Stars: Lost, Missing and Troublesome Stars from the Catalogues of Johannes Bayer, Nicholas Louis de Lacaille, John Flamsteed, and Sundry Others|publisher = The McDonald & Woodward Publishing Company|location = Blacksburg, [[Virginia|VA]]|isbn = 978-0-939923-78-6|pages=231–32}}</ref><!-- referensi untuk tiga kalimat sebelumnya-->

=== Hujan meteor ===
Pavo merupakan [[:en:radiant (meteor shower)|radian]] dari dua [[hujan meteor]] tahunan: [[:en:Delta Pavonids|Delta Pavonids]] dan [[:en:August Pavonids|August Pavonids]].
Delta Pavonids muncul dari tanggal [[21 Maret]] sampai [[8 April]] dan biasanya memuncak sekitar [[5 April|5 atau]] [[6 April]], dianggap berkaitan dengan Komet Grigg-Mellish.{{sfn|Levy|2008|p = 109}} Hujan meteor ini pertama kali ditemukan oleh seorang bernama Michael Buhagiar dari [[Perth]], [[Australia]],<ref>{{cite book|first=Petrus Matheus Marie|last=Jenniskens|title=Meteor Showers and Their Parent Comets|publisher=Cambridge University Press|location=Cambridge, United Kingdom|page=315|date=2006|isbn=978-0-521-85349-1|url=http://books.google.com/books?id=QpajMuyXG8AC&pg=PA315 }}</ref> yang mengamatinya sebanyak enam kali dalam 11 tahun antara [[1969]] dan [[1980]].<ref>{{cite web|url=http://meteorshowersonline.com/showers/delta_pavonids.html|title=Delta Pavonids|last=Kronk|first=Gary W.|work=Meteor Showers Online|publisher=self-published|accessdate=26 August 2013|archive-date=2013-09-28|archive-url=https://web.archive.org/web/20130928035123/http://meteorshowersonline.com/showers/delta_pavonids.html|dead-url=yes}}</ref>
August Pavonids memuncak sekitar 31 Agustus dan dianggap berkaitan dengan komet sejenis [[Komet Halley]], yaitu Komet Levy (P/1991 L3).{{sfn|Levy|2008|p = 117}}
