Daftar gugus terbuka

Gugus terbuka Messier 6 di rasi bintang Skorpio juga dikenal dengan anma Gugus Kupu-Kupu, atau NGC 6405.
Berikut adalah daftar gugus terbuka di Bima Sakti. Gugus terbuka adalah sebuah perkumpulan sampai seribu buah bintang yang semuanya terbentuk dari awan molekuler besar yang sama. Terdapat lebih dari 1000 gugus terbuka yang diketahui di galaksi Bima Sakti, namun jumlah aslinya dapat sampai lebih dari 10 kali lipat lebih banyak. Waktu paruh yang diperkirakan dari gugusan-gugusan ini, yaitu waktu yang diperlukan sampai setengah dari anggota suatu gugusan hilang, berkisar antara 150 sampai 800 juta tahun, tergantung kepadatan awal gugusan.
