2159 Kukkamäki, provisional designation 1941 UX, is a small asteroid from the inner parts of the asteroid belt, about 11 kilometers in diameter. It was discovered by Finnish astronomer Liisi Oterma at Turku Observatory on 16 October 1941.[5]

The stony S-type asteroid has an albedo of about 0.3.[4] It orbits the Sun at a distance of 2.4–2.6 AU once every 3 years and 11 months (1,429 days). The non-eccentric orbit is nearly coplanar with the ecliptic. It takes 4 hours to rotate around its axis.[1]

It is named after Finnish geodesist Tauno Johannes Kukkamäki (1909–1997), who was the director of the Finnish Geodetic Institute for many years and the president of the International Association of Geodesy. He was also a distinguished disciple of Yrjö Väisälä.[2]
