15415 Rika, provisional designation 1998 CA1, is a bright background asteroid from the Florian region of the inner asteroid belt, approximately 3 kilometers (2 miles) in diameter. It was discovered on 4 February 1998, by Japanese astronomer Akimasa Nakamura at the Kuma Kogen Astronomical Observatory in southern Japan.[1] The presumed S-type asteroid has a rotation period of 6.36 hours and possibly an elongated shape.[4] It was named after Rika Akana, a character in the Japanese film and later television adapted drama Tokyo Love Story.[1]
