}}{{Starbox end}}12 Lyncis (12 Lyn) is a star in the constellation Lynx. Its combined apparent magnitude is 4.87. When seen through a telescope, it can be separated into three stars: two components with magnitudes 5.4 and 6.0 that lie at an angular separation by 1.8″ (as of 1992) and a yellow-hued star of magnitude 7.2 at a separation of 8.6″ (as of 1990).[[6] The orbit of the two brighter stars is not known with certainty, but appears to have a period of somewhere around 700 to 900 years.[7] Parallax indicates the system is 210 ± 10 light years distant from Earth.[1]]References1. ^1 2 3 4 5 {{cite journal|title=Validation of the new Hipparcos reduction |url=http://www.aanda.org/index.php?option=com_article&access=bibcode&Itemid=129&bibcode=2007A%2526A...474..653VFUL |author=van Leeuwen, F. |display-authors=etal |journal=Astronomy and Astrophysics |volume=474 |issue=2 |pages=653–664 |date=2007 |arxiv=0708.1752 |bibcode=2007A&A...474..653V |doi=10.1051/0004-6361:20078357 |deadurl=yes |archiveurl=https://web.archive.org/web/20160402233353/http://www.aanda.org/index.php?option=com_article&access=bibcode&Itemid=129&bibcode=2007A&A...474..653VFUL |archivedate=2016-04-02 |df= }}
