192 Nausikaa is a large main-belt S-type asteroid. It was discovered by Johann Palisa on February 17, 1879 at Pula, then in Austria, now in Croatia. The name derives from Nausicaä, a princess in Homer's Odyssey.
Based on the lightcurve data obtained from Nausikaa, a possible satellite was reported in 1985. However, this has not been confirmed. A shape model of Nausikaa has been constructed, also based on the lightcurve data. It indicates a roughly cut, but not very elongated body. In 1998 an occultation of a star by the asteroid was observed from the United States.
Nausikaa's orbital period is 3.72 years, its distance from the Sun varying between 1.81 and 2.99 AU. The orbital eccentricity is 0.246. Nausikaa brightened to magnitude 8.3 at a quite favorable opposition on 2 September 2011, when it was 1.875 AU from the Sun and 0.866 AU from the Earth.
