The Horus belt beta is the second asteroid belt from the sun of the Horus system, United Empire of Earth (UEE). In contrast to its neighboring belt, it sees little commercial traffic aside from passing trade ships despite being located closer to the system's only inhabited planet Serling (Horus I). Marie Sante, who discovered the Horus system, kept a personal base on the largest asteroid in the Horus belt beta that she utilized when exploring the system's outer reaches. Left abandoned after her 2545 disappearance, the base was re-discovered in 2977 and was declared a cultural heritage site.
