'''Gliese 876''', juga disebut '''IL Aquarii''', adalah [[bintang]] [[katai merah]] sejauh 15 tahun cahaya di rasi bintang [[Aquarius]]. Pada tahun 2008, telah dikonfirmasi bahwa terdapat tiga [[planet luar surya]] yang mengorbit bintang ini. Dua dari planet tersebut mirip dengan [[Jupiter]], sementara planet terdekat diduga sebagai [[Neptunus]] kecil atau [[Bumi]] besar. Kemudian pada tanggal 23 Juni 2010, kembali ditemukan sebuah planet mengelilingi bintang ini
