Följeslagaren DH Tauri B eller b har en massa som uppskattas vara mellan åtta och 22 jupitermassor, vilket gör den till antingen en superjupiter eller brun dvärg.[8] Andra källor ger en massa så hög som 0,03 solmassa, med en bolometrisk ljusstyrka på 0,01 gånger solens.[9] Spektraltypen har klassificerats som M7.5[9] eller M9.25.[10] Följeslagaren samlar, medan dess värdstjärna fortfarande har en protoplanetär skiva, fortfarande material och omges av en stoftskiva (möjligen en cirkumplanetär skiva, beroende på dess bildningshistoria).[11]
