 Riwayat hidup 
Abdul Rahman Al-Sufi adalah salah satu dari sembilan astronom Muslim terkenal. Namanya menyiratkan bahwa dia berasal dari kalangan Sufi. Dia tinggal di istana Emir Adud ad-Daula di Isfahan, Persia, dan bekerja menerjemahkan dan meneliti karya astronomi Yunani Kuno, terutama Mathematike Syntaxis oleh Ptolemaeus. Dia menyumbangkan beberapa koreksi pada daftar bintang oleh Ptolemaeus dan melakukan perkiraan kecerahan dan magnitudonya sendiri yang sering menyimpang dari yang ada dalam karya Ptolemaeus, dengan hanya 55% magnitudo Al-Sufi yang identik dengan magnitudo Ptolemaeus

Dia adalah penyumbang utama penerjemahan astronomi Helenistik ke dalam bahasa Arab yang berpusat di Iskandariyah, Mesir, yang pertama mencoba menghubungkan istilah Yunani dengan nama-nama bintang dan rasi Arab tradisional, yang sama sekali tidak berhubungan dan tumpang tindih dengan cara yang rumit.

 Kehormatan 
Sejak 2006, Masyarakat Astronom Iran – Komite Amatir (ASIAC) mengadakan Kompetisi Pengamatan Sufi untuk mengenang Al-Sufi. Kompetisi pertama diadakan pada tahun 2006 di utara Provinsi Semnān dan yang kedua diadakan pada musim panas 2008 di Ladiz dekat Zahedan. Lebih dari 100 peserta dari Iran dan Irak berpartisipasi dalam acara tersebut.رقابت صوفي، درآمدي بر سال جهاني نجوم
