    1830 Pogson, provisional designation 1968 HA, is a main-belt asteroid discovered on April 17, 1968, by Paul Wild at Zimmerwald Observatory, Switzerland. The S-type asteroid with a relatively low eccentricity of 0.05 orbits the Sun at a distance of 2.1–2.3 AU every 3 years and 3 months. It had been assigned a large number of provisional designations dating back as far as 1926.[1]

    It was named after the English astronomer Norman Pogson (1829–1891), inventor of the modern astronomical magnitude scale and discoverer of eight minor planets, including 42 Isis and 67 Asia.[2]
