'''2MASS J15074769−1627386''' (也縮寫為 '''2MASS 1507−1627''') 是位於[[天秤座]]的一顆棕矮星，距離地球約24.1光年。屬於光譜等級L5；它的表面溫度為1,300至2,000[[開氏|K]]。與其他L型棕矮星一樣，它的光譜主要由金屬氫化物和鹼金屬組成。其光譜還具有較弱的矽酸鹽吸收帶和高度變化的水吸收帶，表明具有復雜的雲霧結構。<ref>{{citation|arxiv=1411.2911|year=2014|doi=10.1088/2041-8205/798/1/L13|last1=Yang|first1=Hao|last2=Apai|first2=Dániel|last3=Marley|first3=Mark S.|last4=Saumon|first4=Didier|last5=Morley|first5=Caroline V.|last6=Buenzli|first6=Esther|last7=Artigau|first7=Étienne|last8=Radigan|first8=Jacqueline|last9=Metchev|first9=Stanimir|last10=Burgasser|first10=Adam J.|last11=Mohanty|first11=Subhanjoy|last12=Lowrance|first12=Patrick J.|last13=Showman|first13=Adam P.|last14=Karalidi|first14=Theodora|last15=Flateau|first15=Davin|last16=Heinze|first16=Aren N.|title=HST Rotational Spectral Mapping of Two L-Type Brown Dwarfs: Variability in and Out of Water Bands Indicates High-Altitude Haze Layers |journal=The Astrophysical Journal|volume=798|pages=L13|s2cid=26179429}}</ref>
