    254 Augusta is a main-belt asteroid, discovered on March 31, 1886 by astronomer Johann Palisa at Vienna Observatory, Austria. The stony S-type asteroid measures about 12 kilometers in diameter.[1]

    It is the first-numbered member of the Augusta family, after which the small Asteroid family and subgroup of the main-belt has been named.

    Augusta was named after the German–Austrian writer Auguste von Littrow (1819–1890), widow of astronomer Carl Ludwig von Littrow, who was a former director of the Vienna Observatory.[2]
