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.

There are 2 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Leo Minor.

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.
