'''Bintang Pistol''' ([[Bahasa Inggris|Inggris]]: ''Pistol Star''), juga dikenal sebagai '''V4647 Sagittarii''', adalah [[Hyper Raksasa|hyper raksasa biru]] yang berjarak sekitar 25.000 tahun cahaya dari Bumi di rasi bintang [[Sagitarius|Sagittarius]] dan 100 tahun cahaya dari pusat galaksi kita. Ini adalah bintang yang sangat bercahaya dan masif yang ditemukan pada tahun 1990 di pusat Nebula Pistol. Bintang ini memiliki jari-jari 300 kali radius matahari dan memiliki suhu permukaan sekitar 11.800 [[Kelvin|K]]. Ini adalah kandidat [[Bintang variabel|variabel]] bercahaya biru ([[Klasifikasi bintang|cLBV]]) dan salah satu bintang paling bercahaya yang diketahui, dengan [[luminositas]] 1.600.000 kali Matahari.<ref name=":0">{{Cite web|url=https://www.constellation-guide.com/pistol-star/|title=Pistol Star and Nebula – Constellation Guide|language=en-US|access-date=2020-07-21}}</ref><ref name=":1">{{Cite web|url=http://www.solstation.com/x-objects/pistol.htm|title=Pistol Star|website=www.solstation.com|access-date=2020-07-21}}</ref><ref>{{Cite web|url=http://astronesia.blogspot.com/2013/07/mengenal-bintang-pistol-si-maha-raksasa.html|title=Mengenal Bintang Pistol Si Maha Raksasa Biru - Berita Astronomi|last=|first=|date=|website=|language=en|access-date=2020-07-23}}</ref>
