'''61 Cygni''' merupakan [[bintang ganda]] di rasi [[Cygnus]]. Bintang ini terdiri dari dua [[bintang katai]] tipe K (''K-type dwarf'') yang saling mengorbit. 61 Cygni adalah salah satu bintang yang menarik untuk diteliti oleh para astronom. Pada tahun 1838, [[Friedrich Wilhelm Bessel]] mengukur jarak antara keberadaanya dengan [[Bumi]], dan menghasil angka sekitar 10.4 [[tahun cahaya]], lebih dekat daripada hasil yang diperoleh pada pengujian terakhir (11.4 [[tahun cahaya]]).<ref name="Bessel">{{cite web▼
