[3] The presumed C-type asteroid has a rotation period of 10.0 hours and measures approximately 22 kilometers (14 miles) in diameter.

[2] When applying the synthetic hierarchical clustering method (HCM) by Nesvorný, or the 1995 HCM-analysis by Zappalà,[6] Kaye is a non-family asteroid of the main belt's background population,[5][6] while according to another HCM-analysis by Milani and Knežević (AstDyS),[7] it is a core member of the Ursula family (631), a family of 1,500 asteroids with a C- and X-type.

[2] Kaye starred in popular feature films such as The Court Jester (1956), typically playing the role of a gentle bumbler who triumphs eventually.

[12] In August 2012, two rotational lightcurves of Kaye were obtained from photometric observations at the Palomar Transient Factory in California.

Lightcurve analysis gave a rotation period of 10.0059±0.0569 and 10.0186±0.0569 hours with a brightness variation of 0.32 and 0.34 magnitude in the R and S-band, respectively (U=2/2).
