13241 Biyo, provisional designation 1998 KM41, is a background asteroid from the Flora region of the inner asteroid belt, approximately 4 kilometers (2.5 miles) in diameter. It was discovered on 22 May 1998, by the Lincoln Near-Earth Asteroid Research team (LINEAR) at the U.S. Lincoln Laboratory Experimental Test Site in Socorro, New Mexico. The presumed S-type asteroid has a rotation period of 4.4 hours and likely an elongated shape.[6] It was later named after Filipino educator Josette Biyo.[1]
