46 Leonis Minoris (abbreviated 46 LMi), also named Praecipua {{IPAc-en|p|r|I|'|s|I|p|j|U|@}},{{cite web | url=https://www.iau.org/public/themes/naming_stars/ | title=Naming Stars |publisher=IAU.org |access-date=16 December 2017}} is the brightest star in the constellation of Leo Minor. It is of spectral class K0+III-IV and of magnitude 3.83. It is a red clump giant. Based upon parallax measurements, its distance from the Sun is approximately 99.1 light-years. It is a suspected variable with an amplitude of about 0.05 magnitudes.
Nomenclature
46 Leonis Minoris is the star's Flamsteed designation. It is sometimes designated "o LMi" (not "ο LMi"), from Bode's catalogue of 1801. It was presumably intended to be designated α, as Francis Baily decided to letter each star brighter than magnitude 4.5, but the designation was missing from his catalogue, even though the dimmer β was included.{{cite book

It bore the traditional proper name Praecipua, derived from the Latin for "the Chief (Star of Leo Minor)".{{cite book

}} The name may originally have referred to 37 Leonis Minoris, and later mistakenly transferred to this star.[http://www.ianridpath.com/startales/leominor.htm Leo Minor: The little lion]- Ian Ridpath's Star Tales In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN){{cite web | url=https://www.iau.org/science/scientific_bodies/working_groups/280/ | title=IAU Working Group on Star Names (WGSN)|access-date=22 May 2016}} to catalog and standardize proper names for stars. The WGSN approved the name Praecipua for this star on 30 June 2017 and it is now so included in the List of IAU-approved Star Names.
It is known as 勢四, "the Fourth (Star) of the Eunuch", in traditional Chinese astronomy.{{citation needed|date=November 2016}}
