Orbit of the asteroid Akhat and its position in the solar system
Photometric observations made in 1996 allowed us to obtain the light curves of this body, from which it followed that the period of rotation of the asteroid around its axis is 5.949 ± 0.014 hours, with a change in brightness as it rotates 0.20 ± 0.01 m [2] .
