3031 Houston is a main-belt asteroid discovered on February 8, 1984 by Edward L. G. ("Ted") Bowell at the Lowell Observatory, Anderson Mesa Station. It is named after Walter Scott Houston, an American amateur astronomer.
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.
