[3] The primitive P-type asteroid has a rotation period of 17.1 hours and measures approximately 101 kilometers (63 miles) in diameter.

[3] On the same night, the asteroid was independently discovered by South African astronomer Cyril Jackson at Johannesburg Observatory.

[13] In the Tholen classification, Abastumani is a primitive, carbonaceous P-type asteroid, a common spectral type in the outer main-belt and among the Jupiter trojan population.

[1] In April 2002, a rotational lightcurve of Abastumani was obtained from photometric observation by astronomer John Gross at the U.S. Sonoran Skies Observatory (G94) in Benson, Arizona.

[7][8][9] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, i.e. a diameter of 101.5 kilometers and an albedo of 0.0298.
