67P/Churyumov–Gerasimenko (yoki Churyumov–Gerasimenko kometasi; rus. Комета Чурюмова — Герасименко) Quyosh tizimidagi kometa boʻlib, orbital davri 6,45 yil,[1] oʻz oʻqi atrofida aylanish davri 12,4 soat[5] va tezligi 135 000 km/soat ga teng.[6] Keyingi perifeliyiga (orbitasining Quyoshga eng yaqin nuqtasiga) 2015-yil 13-avgustda keladi.[7][8][9] Boshqa kometalar kabi uni ochganlar — Klim Churyumov va Svetlana Gerasimenko sharafiga shunday nomlangan, Churyumov va Gerasimenko kometani 1969-yil Almatidagi observatoriyada suratga olishgan.

Churyumov–Gerasimenko Yevropa kosmik agentligi 2004-yil 2-martda uchirgan Rosetta apparati manzilidir.[10][11][12] Rosetta 2014-yil 6-avgustida Churyumov–Gerasimenko kometasiga uchib keldi[13][14] va 2014-yil 10-sentabrida orbitasiga kirdi.[15] Rosettaning Philae nomli qoʻnuvchi apparati 2014-yil 12-noyabrda kometa sirtiga qoʻndi, va tarixda kometa yadrosiga qoʻngan birinchi apparat boʻldi.[16][17][18]
