[[File:NGC 6888 HOO By Don Christopher Deaver.jpg|thumb|left|在[[NGC 6888]]中心的WR 136。]]

'''WR 136'''是位於[[天鵝座]]的一顆[[沃爾夫-拉葉星]]。它位於[[眉月星雲]]的中心。據估計，它的年齡約為470萬年，已經接近生命的盡頭。預計在幾十萬年內，它將爆炸成為[[超新星]]<ref name=moore/>。

根據最近的估計，WR 136比[[太陽]]亮60萬倍，質量大21倍，直徑大5.1倍。它的[[有效溫度|表面溫度]]約為70,000[[卡爾文|k]]<ref name=hamann/>。

WR 136在大約120,000–240,000年前成為[[紅超巨星]]時，吹掉了一個質量約為{{solar mass|5}}的物質外殼，並且仍在以80公里/秒的速度膨脹<ref name=ngc6888>{{cite journal|bibcode=2014ApJ...785..100M|title=The Trace of the CNO Cycle in the Ring Nebula NGC 6888|journal=The Astrophysical Journal|volume=785|issue=2|pages=100|last1=Mesa-Delgado|first1=A.|last2=Esteban|first2=C.|last3=García-Rojas|first3=J.|last4=Reyes-Pérez|first4=J.|last5=Morisset|first5=C.|last6=Bresolin|first6=F.|year=2014|doi=10.1088/0004-637X/785/2/100|arxiv = 1402.6181 |s2cid=118596124}}</ref>。現時，它的快速[[星風|恆星風]]以約380萬英里/小時（1700公里/秒）的速度從恆星噴出<ref>{{cite journal|bibcode=1994A&A...281..184H|title=Non-LTE spectral analyses of Wolf-Rayet stars: The nitrogen spectrum of the WN6 prototype HD 192163 (WR136)|url=https://archive.org/details/sim_astronomy-and-astrophysics_1994-01-01_281_1/page/184|journal=Astronomy and Astrophysics |issn=0004-6361|volume=281|pages=184|last1=Hamann|first1=W.-R.|last2=Wessolowski|first2=U.|last3=Koesterke|first3=L.|year=1994}}</ref>，正在追趕早先從恆星噴出的物質，並將其塑造成一個外殼。從WR 136炙熱表面發射的[[紫外線]]使外殼發光<ref name=ngc6888/>。

有一些證據表明WR 136可能是一對[[聯星]]。它的伴星是一顆[[恆星分類]][[K型主序星|K]]或[[紅矮星|M]]的低質量恆星，每5.13天繞沃夫-瑞葉星一周，是[[X射線聯星#低質量X射線聯星|低質量X射線聯星]]系統的前身<ref name="lmxb">{{Cite journal
