'''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 a system with at least two planets, [[Madrigal]] and [[Hesiod]]. Hesiod is the only gas giant orbiting 23 Librae.

==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.
