(152647) Rinako is a main inner belt asteroid discovered by Japanese amateur astronomer Atsuo Asami on October 29, 1997 at Hadano Observatory ( IAU code 355) in Kanagawa Prefecture .
The mean diameter of the asteroid was roughly calculated to be 3.128 (± 0.471) km . The orbit of (152647) Rinako around the sun has a high eccentricity of 0.2528 .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (152647) Rinako assumed a dark surface, so it could, roughly speaking, be trade a C asteroid .
(152647) Rinako was named on July 30, 2007 after the discoverer's daughter: Rinako Asami (* 1993).
