Leo Minor (Pronounciation:Lee-o Mine-nore, Abbrev:LMi, Latin:Leonis Minoris) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Leo Minor takes up 231.956 sq. degrees of the night sky which equates to 0.56% of the night sky. Leo Minor is the 64th largest in terms of size in the night sky.
The constellation name means The Small Lion . It was not one of the original constellations that had been devised by Ptolemy, instead it was created by Johannes Hevelius years later.
There are 4 stars that make up the main constellation. The hipparcos satellite scanned and detailed 607 stars. There are 22 stars that can be seen with the naked eye in the constellation on a very clear night sky.
Leo Minor is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Leo Minor is a northern hemispheric constellation which means it can't be seen easily or at all from the southern hemisphere.
The distance to Leo Minor is not calculable because all the stars that make up the constellation are at various distances. The best answer for distance to Leo Minor is to calculate the average distance of the stars.
There are no deep space objects that were identified by Charles Messier in this constellation. There are no non-Messier deep space objects in this constellation that are covered at present on this site.

The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.
The nearest star to Earth is 11 Leonis Minoris which is roughly about 37.08 Light Years from the Earth. The nearest star to the Earth with an exoplanet is HD 87883 which is about 59.38 Light Years.
The furthest star that is located in the constellation is HIP 47579 and it is 326163.3 light years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.
The brightest star in Leo Minor is Praecipua and is located about 112.13 light years from the Sun. The star has a apparent magnitude of 3.79 but an absolute magnitude of 1.47 when the star is viewed from a distance of 10 Parsecs or 32.6 Light Years. There is no star in the constellation with an Alpha Bayer Designation, there is only Beta Leonis Minoris and that is the second brightest star in Leo Minor.
The dimmest star that can be seen in Leo Minor with the naked eye is 33 Leonis Minoris. The dim star has an apparent magnitude of 5.9. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan.
