2042 Sitarski (4633 P-L) is a main-belt asteroid discovered on September 24, 1960 by Cornelis Johannes van Houten, Ingrid van Houten-Groeneveld and Tom Gehrels at Palomar Observatory. It is named after Grzegorz Sitarski, polish astronomer.

This object is a member of the Merxia family of asteroids that share similar orbital elements and physical properties. This family was named after the asteroid 808 Merxia. They most likely formed from the breakup of a basalt object, which in turn was spawned from a larger parent body that underwent igneous differentiation.[1]
