'''HD 107914''' is the primary component of a [[binary star system]] in the constellation [[Centaurus]], with an estimated distance of {{Convert|255.5|ly|pc|lk=on}}<ref name=Potemine2010/> 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 (hypothetical star)|Nemesis]]" star since it may pass through the [[Oort cloud]] in the future.<ref name=Potemine2010>{{cite arXiv | first=Igor Yu. | last=Potemine | date=2010-04-13 | eprint=1003.5308 | title=Giant Nemesis candidate HD 107914 / HIP 60503 for the perforation of Oort cloud | class=astro-ph.SR <!--bibcode=2010arXiv1003.5308P--> }}</ref> 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 [[stellar spectrum|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.<ref>{{cite journal |doi=10.1086/521231 |last=Eaton |first=J. A. |author2=Williamson M.

For example, if ''V<sub>r</sub>'' = –10 km/s, then the distance from the Sun to HD 107914 at closest approach will be about {{Convert|5.2|ly|pc|abbr=on|lk=off}}.
