70 Virginis is a yellow dwarf star that is around 58 light-years away from the Earth in the constellation Virgo. 70 Virginis is not as big or hot as Earth's Sun.[1]

In 1996, 70 Virginis was found to have an extrasolar planet in orbit around it.[2] There is also a dust disc that orbits the star. The temperature of the disc is 156 K and it is about 3.4 AU from the star.[3]
