46 Leonis Minoris

Star in the constellation of Leo Minor

Star in the constellation of Leo Minor

| b-v = | u-b = 46 Leonis Minoris (abbreviated 46 LMi), also named Praecipua , 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 |author-link = Richard Hinckley Allen

It is known as 勢四, "the Fourth (Star) of the Eunuch", in traditional Chinese astronomy.
