K-type main-sequence star
In 2011, it was noticed that the faint K-type main-sequence star HD 125354 had a similar proper motion throughout space, and was likely physically associated. Another 2015 paper supported this hypothesis. The star, which is located 1.2 ly (0.37 pc) away from Iota Virginis, also has a similar distance from the Sun, within the margin of error. It itself is a close binary with another star separated 0.33″ from the main star.
