976 Benjamina

[2] Benjamina is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.

[3] In September 2004, a rotational lightcurve of Benjamina was obtained from photometric observations by French amateur astronomer Laurent Bernasconi.

Follow-up observation by his college René Roy in March 2018, determined a concurring period of 9.705±0.003 hours but with a much higher amplitude of 0.60±0.10 magnitude (U=2).

It showed a sidereal period of 9.7080±0.0002 hours, and gave a spin axis at (354.0°, 80.0°) in ecliptic coordinates (λ, β).

[5][10] The Collaborative Asteroid Lightcurve Link adopts the result from IRAS, that is, an albedo of 0.0559 and a diameter of 80.53 kilometers based on an absolute magnitude of 9.22.

An 11 Chord plot of the occultation by Benjamina observed on 19 July 2003 from sites in Australia, New Zealand and Argentina.
