Leonis Minoris system was a star system colonized by the United Nations Space Command. It was home to three colony planets in the 2500s.[1]


In 2537, the star system and its colonies were attacked and glassed by the Covenant, with the UNSC rushing to their defense. Although UNSC naval losses were considered minimal, two of the colonies were razed by the Covenant. These two colonies had been sacrificed in order to defend the third colony.[citation needed]


  • The name Leonis Minoris is applied to multiple stars in the real life. These range from the numbered stars like 10 Leonis Minoris to the lettered R Leonis Minoris. All of these stars are in the Leo Minor constellation.
