    1830 Pogson, provisional designation 1968 HA, is a stony asteroid from the inner regions of the asteroid belt, approximately 7 kilometers in diameter.

    The asteroid was discovered on 17 April 1968, by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland. The S-type asteroid orbits the Sun in the inner main-belt at a distance of 2.1–2.3 AU once every 3 years and 3 months (1,182 days). Its orbit has an eccentricity of 0.06 and an inclination of 4° with respect to the ecliptic.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]

    This minor planet 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]
