    1747 Wright, provisional designation 1947 NH, is a stony asteroid and a sizable Mars-crosser from the innermost regions of the asteroid belt, about 6 kilometers in diameter. It was discovered on July 14, 1947, by American astronomer Carl Wirtanen at Lick Observatory on Mount Hamilton near San Jose, California.[10]

    The S-type asteroid is classified as an AU and Sl-type in the respective Tholen and SMASS classification scheme. It the orbits the Sun at a distance of 1.5–1.9 AU once every 2 years and 3 months (816 days). Its orbit shows an eccentricity of 0.11 and is notably tilted by 21 degrees to the plane of the ecliptic. It has a well-define rotation period of 5.29 hours.[6][7][8][9] According to the surveys carried out by the Infrared Astronomical Satellite, IRAS, and the Japanese Akari satellite, it has a geometric albedo of 0.20 and 0.32, respectively.[4][5]

    The minor planet was named in memory of American astronomer William Hammond Wright (1871–1959), staff member and later director of the Lick Observatory until 1942. He was a pioneer in astrophysics with his last project being the design and construction of the 20-inch Carnegie double astrograph for the proper motion program he initiated. As a by-product several discoveries of asteroids and comets were made. He is also honored by the Martian and lunar craters Wright.[2]
