It was discovered on 19 July 1925, by Soviet astronomer Vladimir Albitsky at the Simeiz Observatory on the Crimean peninsula.
[4][a] In May 2002, two rotational lightcurves of Mussorgskia were obtained from photometric observations by Stephen Brincat at the Flarestar Observatory in Malta and by French amateur astronomer René Roy.
Lightcurve analysis gave a rotation period of 5.519 and 5.6362 hours with a brightness amplitude of 0.20 and 0.21 magnitude, respectively (U=2/3).
[10][11] The Collaborative Asteroid Lightcurve Link adopts a period of 5.636 hours and a brightness variation between 0.2 and 0.21 magnitude (U=3).
[6][7][8][9] CALL assumes a standard albedo for carbonaceous asteroids of 0.057 and consequently calculates a larger diameter of 36.78 kilometers based on an absolute magnitude of 10.9.
