39 Laetitia

It is orbiting the Sun with a period of 4.61 years and is spinning on its axis once every 5.1 hours.

Photometric observations of this asteroid gathered between 1968 and 1974 were used to build a light curve that provided shape and rotation information.

It has the general shape of an elongated triaxial ellipsoid with ratios between the lengths of the axes equal to 15:9:5.

[9] 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.

[10] Photometric observations collected during 2006–08 were used to measure time variations of the asteroid light curve.
