Nausikaa [5] ( minor planet designation: 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.
This is an S-type asteroid around 86 km with an elliptical ratio of 1.51. The sidereal rotation period is 13.6217 hours. [6]
Based on the lightcurve data obtained from Nausikaa, a possible satellite was reported in 1985. However, this has not been confirmed. [7] A shape model of Nausikaa has been constructed, also based on the lightcurve data. It indicates a roughly cut, but not very elongated body. [8] In 1998 an occultation of a star by the asteroid was observed from the United States.
In 1988 a search for satellites or dust orbiting this asteroid was performed using the UH88 telescope at the Mauna Kea Observatories, but the effort came up empty. [9]
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.
