La seva situaci al cel est entre Arcturus (Alpha Botes) i Zaniah (Eta Virginis). If two such planets form with a small enough separation, their orbits are unstable, resulting in either a collision or an ejection. Its mass is 7.49 Jupiters, it takes 116.7 days to complete one orbit of its star, and is 0.481 AU from its star. (See a Digitized Sky Survey image of 70 Virginis such as San Francisco State University astronomer Geoffrey W. Marcy who also has helped to discover many extrasolar planets, note that there may in fact be many different physical processes that lead to the formation of planets. [1] The minimum mass ( M 2 sin i ) of 70 Vir "B" is 6.6 Jovian masses ( M J ), which falls in the mass range associated with "extrasolar giant planets" (0.3-15 M J ). The minimum mass (M2 sin i) of 70 Vir "B" is 6.6 Jovian masses (MJ), which falls in the mass range associated with "extrasolar giant planets" (0.3--15 MJ). When first announced, 70 Virginis b was considered to be within its star's habitable zone (preferably in the "Goldilocks zone"), but it was later confirmed that the planet has an eccentric orbit, closer to its parent.

Three small bodies have been found in orbit around the pulsarPSR 1257+12. An extremely low mass companion to the solar-type star 70 Virginis is inferred from the observed periodic Doppler reflex motion of the primary during 8 yr. Elle est anormalement brillante pour son type spectral et pourrait tre juste en train d'voluer vers la phase sous-gante. Au moment de sa dcouverte en janvier 1996, on croyait que l'toile se trouvait seulement 29 al ce qui a fait qu'on a cru que l'toile tait moins lumineuse selon sa magnitude apparente. 70 Virginis b est une exoplante gante gazeuse ayant 7,5 fois la masse de Jupiter et une orbite excentrique de 116 jours autour de son toile parente. 70 Virginis (abbreviated 70 Vir) is the Flamsteed designation of a yellow dwarf star approximately 59 light-years away in the constellation Virgo.
