46 Leonis Minoris is the brightest star
in the constellation
Leo Minor
. It is sometimes known as "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.
It has the proper name Praecipua, the Latin "the Chief (Star of Leo Minor)". The name may originally have referred to 37 Leonis Minoris, and later mistransfered to this star.
It is known as 勢四, "the Fourth (Star) of the Eunuch", in traditional Chinese astronomy.
46 LMi has spectral class
K0+III-IV and is of magnitude
3.83. Its distance from Earth is approximately 98 light years.
Star
A star is a massive, luminous sphere of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth...

Constellation
In modern astronomy, a constellation is an internationally defined area of the celestial sphere. These areas are grouped around asterisms, patterns formed by prominent stars within apparent proximity to one another on Earth's night sky....

46 LMi has spectral class
Stellar classification
In astronomy, stellar classification is a classification of stars based on their spectral characteristics. The spectral class of a star is a designated class of a star describing the ionization of its chromosphere, what atomic excitations are most prominent in the light, giving an objective measure...

The apparent magnitude of a celestial body is a measure of its brightness as seen by an observer on Earth, adjusted to the value it would have in the absence of the atmosphere...
