15258 Alfilipenko, provisional designation 1990 RN17, is a carbonaceous background asteroid from the outer region of the asteroid belt, approximately 12 kilometers in diameter. It was discovered on 15 September 1990, by Russian–Ukraininan astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory, Nauchnyj, on the Crimean peninsula.[8] The asteroid was named after Russian civil engineer Aleksandr Filipenko.[2]
Orbit and classification
