Abstract
The asteroid 153 Kilda was studied by photometric, spectroscopic and p olarimetric observations during the apparition in 1992. The rotation p eriod was determined to 5.11 hours with a lightcurve amplitude of 0.05 magnitudes. From our spectrum we find 153 Hilda to be of taxonomic ty pe P. The polarization value of -0.23 at a phase angle of 3.2 degrees seems normal for a P-type asteroid. Long term integrations of the orbi t shows that it is stable over time intervals of several million years .
