(13239) Kana is an asteroid of the inner main belt , which on 21 May 1998 by the Japanese astronomer Akimasa Nakamura at Kuma-Kōgen Observatory ( IAU code 360) in Kumakogen in Ehime Prefecture on the island of Shikoku was discovered. The asteroid had previously been sighted under the provisional name 1995 VK 10 on November 15, 1995 as part of the Spacewatch project at the Kitt Peak National Observatory in Arizona .

According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (13239) Kana assumed a bright surface, so it could, roughly speaking, be around trade an S asteroid .

(13239) Kana was named after Kana Nakamura, the daughter of Akimasa Nakamura, who was born in 1999 and whose initials are identical to the letter coding of the provisional name of the asteroid, 1998 KN, where the K in the provisional name stands for the date of discovery, in this case the second half of May. The final designation took place on May 23, 2000.
