'''23 Librae''' (23 Lib) is a yellow dwarf star in the constellation [[Wikipedia:Libra|Libra]], and is about 83.7 light-years from the [[Sol system]]. 23 Lib has a mass of 1.05 Suns and a radius of 1.25 Suns.<ref name="wiki">[[Wikipedia:23 Librae|'''Wikipedia:''' ''23 Librae'']]</ref> 

23 Librae is orbited by at least two planets, [[Madrigal]] and [[Hesiod]]. Hesiod is the only gas giant orbiting 23 Librae. Madrigal, the only planet in 23 Librae's habitable zone,<ref>'''[[Halo: The Cole Protocol]]''', ''pages 155-158''</ref> was a human [[Outer Colony]]<ref>'''Halo: The Cole Protocol''', ''page 13''</ref> until the [[Covenant]] arrived and glassed the planet in [[2528]].<ref>'''Halo: The Cole Protocol''', ''page 72''</ref> 

==History==
Madrigal was colonized by [[humanity]], serving as a thriving human colony. It was glassed by the [[Covenant]] in [[2528]]. 

Survivors of the attack fled to the Trojan [[asteroid]]s trailing the gas giant [[Hesiod]], farther out-system. There, they joined [[Insurrectionist]]s in the asteroid colony known as [[the Rubble]].<ref>'''Halo: The Cole Protocol''', ''page 11''</ref> [[Kig-Yar]] merchants established trade relations with the humans in the asteroids while the Covenant plotted to raise an army of [[Unggoy]] on Hesiod's moon [[Metisette]]. Both the Rubble and the Covenant installation on Metisette were destroyed in the [[Battle of the Rubble]] and the [[Battle of Metisette]].<ref>'''Halo: The Cole Protocol''', ''page 311''</ref> However, the human inhabitants of the Rubble managed to escape on [[Habitat Exodus]] with the help of the {{UNSCShip|Midsummer Night}} and [[Gray Team]] while the Covenant forces were completely wiped out by the ''Midsummer Night''.

==Trivia==
The description of the 23 Librae system in ''[[Halo: The Cole Protocol]]'' bears several contradictions with real-world astronomical observations of the system. The novel states that [[Hesiod]] is the only gas giant in the system.<ref>'''Halo: The Cole Protocol''', ''page 158''</ref> However, at least two gas giants have been discovered orbiting the star.<ref name="wiki"/> Furthermore, ''The Cole Protocol'' establishes that Madrigal—a terrestrial planet—is the only planet in the star's habitable zone. In the real world, the gas giant [[Wikipedia:23 Librae b|23 Librae b]] was discovered in 1999 as orbiting 23 Librae in its habitable zone.
