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 eksoplanet 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
