Alternatively, in Nesvorný's HCM-analysis, the asteroid belong's to the main belt's background population, while in an earlier such analysis, Thais Mothé-Diniz considered Akplatonov to be the largest body in a small cluster or clump of its own.
[1] This minor planet was named in honor of Aleksandr Konstantinovich Platonov (born 1931), a Russian computational mathematician, roboticist, astrodynamicist, and long-time member at the Keldysh Institute of Applied Mathematics.
He pioneered the research in walking robots, the computation of satellite orbits around Earth, and the guidance of the flight path of spacecraft in the Solar System.
[11] A rotational lightcurve of Akplatonov was obtained from photometric observations using the 0.9-meter SARA telescope at Kitt Peak National Observatory in May 2009.
[12] According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, Akplatonov measures 8.2 kilometers in diameter and its surface has an albedo of 0.285,[7][8][9] while the Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.21 – derived from 15 Eunomia, the family's largest member and namesake – and calculates a diameter of 9.17 kilometers using an absolute magnitude of 12.5.
