1478 Vihuri, provisional designation 1938 CF, is a stony asteroid from the inner regions of the asteroid belt, about 10 kilometers in diameter. It was discovered by Finnish Yrjö Väisälä at Turku Observatory on 6 February 1938.[7]
The S-type asteroid orbits the Sun at a distance of 2.2–2.7 AU once every 3 years and 10 months (1,415 days). Its orbit shows an eccentricity of 0.09 and is tilted by 8 degrees to the plane of the ecliptic. It has a rotation period of 19.5 hours[6] and an albedo of 0.13, according to the surveys carried out by Akari and WISE/NEOWISE.[4][5]
The minor planet was named after Finnish ship owner and supporter of science and arts, A. Vihuri.[2]
