1534 Näsi
1534 Näsi, provisional designation 1939 BK, is a rather eccentric, carbonaceous asteroid from the outer region of the asteroid belt, about 22 kilometers in diameter. It was discovered by Finnish astronomer Yrjö Väisälä at Turku Observatory, Southwest Finland, on 20 January 1939.〔 The C-type asteroid, classified as a Cgh-subtype in the SMASS taxonomy, orbits the Sun at a distance of 2.0–3.4 AU once every 4 years and 6 months (1,647 days). Its orbit shows a notable eccentricity of 0.25 and is tilted by 10 degrees to the plane of the ecliptic. It has a rotation period of 7.9 hours〔〔 superseding an earlier observation from the 1990s that gave a somewhat longer period.〔 According to the surveys carried out by IRAS, Akari, and WISE/NEOWISE, the body has an albedo between 0.04 and 0.10.〔〔〔 The minor planet's name is derived from the Finnish lake Näsijärvi, sometimes called "Näsi". The large lake measures 256 square kilometres (99 sq mi) in size and is located only 95 metres above sea level.〔 == References ==
