70 Virginis (disingkat 70 Vir) adalah bintang katai kuning yang berjarak sekitar 59 tahun cahaya^[4] di konstelasi Virgo. Bintang ini memiliki cahaya luar biasa cerah untuk jenis spektral dan mungkin baru mulai berkembang ke fase raksasa merah.

Pada tahun 1996, 70 Virginis diketahui memiliki eksoplanet yang mengorbit mengelilinginya.^[10] Ada juga piringan debu dengan suhu maksimum 153 K terletak pada jarak 3,4 AU dari bintang.^[11]

Sistem planet

Penemuan planet di sekeliling 70 Virginis diumumkan pada 17 Januari 1996 pada pertemuan American Astronomical Society di San Antonio, Texas. Planet itu terdeteksi menggunakan pengukuran kecepatan radial yang diambil dengan teleskop C. Donald Shane di Observatorium Lick.^[10]^[12]
