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. The constellation gets its name as it 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.
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 number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Leo Minor is 607. The number of stars that are of magnitude 6.0 or lower in the constellation is 22. The number of stars in the constellation that make up the outline is 4.
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 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 can be located in the constellation is HIP 47579 which is located about 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 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
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.
Created by Johannes Hevelius in around 1687 and recognised by the International Astronomical Union.
There are 8 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
