Messier 92 adalah salah satu gugusan bola yang paling terang dibelahan [[Bumi]] utara, tetapi Messier 92 sering terlewatkan oleh atronom amatir karena kedekatannya terhadap [[Messier 13]] yang lebih spektakuler. Messier 92 dapat dilihat dengan mata telanjang pada kondisi yang sangat bagus.<ref name=maa/> |

Messier 92 (juga dikenal dengan M92 atau NGC 6341) adalah sebuah gugus bola dari bintang disebelah utara constellation Hercules. Messier 92 di temukan oleh Johann Elert Bode pada 1777, dan kemudian dipublikasikan Jahrbuch pada 1779.[8] Gugusan ini secara terpisah ditemukan oleh Charles Messier pada 18 Maret, 1781 dan dimasukkan dalam urutan ke 92 pada katalognya.[9] M92 berjarak sekitar 26.700 tahun cahaya jauhnya dari Bumi.
Messier 92 adalah salah satu gugusan bola yang paling terang dibelahan Bumi utara, tetapi Messier 92 sering terlewatkan oleh atronom amatir karena kedekatannya terhadap Messier 13 yang lebih spektakuler. Messier 92 dapat dilihat dengan mata telanjang pada kondisi yang sangat bagus.[10]
