HD 107914 is the primary component of a binary star system in the constellation Centaurus, with an estimated distance of Шаблон:Convert[1] from the Solar System. It has a stellar classification of A7-8 III, making it a giant star.

Measurement of the proper motion of this system show that it has a low transverse velocity relative to the Sun. For this reason, it has been compared to the hypothetical "Nemesis" star since it may pass through the Oort cloud in the future.[1] The star is too far away to be a companion to the Sun. However, preliminary measurements of the H-alpha line in the star's spectrum show a radial velocity in the range from –13 to +3 km/s. (This result was obtained by M. Muterspaugh and M. Williamson at a robotic spectroscopic telescope in Arizona.[2]) Such values for the radial velocity are too small to produce a likely collision course with the Solar System. For example, if Vr = –10 km/s, then the distance from the Sun to HD 107914 at closest approach will be about Шаблон:Convert.
