From Minor Planet Circular 10845:
Named in honor of Walter Scott Houston, American amateur astronomer well known for his column Deep-Sky Wonders in the magazine Sky & Telescope. Houston has specialized in the visual study of deep-sky objects and has guided countless amateurs to view and marvel at the varied objects within the grasp of small telescopes. Name proposed by the discoverer following a suggestion by P. L. Dombrowski.
