6349 Acapulco, provisional designation 1995 CN1, is a stony asteroid from the middle region of the asteroid belt, roughly 15 kilometers in diameter. It was discovered on 8 February 1995, by Japanese astronomer Masahiro Koishikawa at the Ayashi Station of the Sendai Astronomical Observatory in the Tōhoku region of Japan.[5]
The S-type asteroid orbits the Sun at a distance of 2.3–3.0 AU once every 4 years and 4 months (1,590 days). Its orbit shows an eccentricity of 0.14 and is tilted by 11 degrees to the plane of the ecliptic. In 2010, a photometric light-curve analysis at the Palomar Transient Factory gave a rotation period of 4.3755±0.0020 hours with a brightness amplitude of 0.18 in magnitude.[4] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.10, which is an unusually low value for an asteroid classified as S-type.[3]
The minor planet is named for the city of Acapulco, Mexico, a famous resort and well known as one of the three most beautiful ports in the world. Since 1973, Acapulco is the international sister city of Sendai, Japan, where the discovering observatory is located, and after which the minor planet 3133 Sendai is named. Hasekura Tsunenaga (1571–1622), the retainer of the famous Japanese feudal lord Date Masamune who founded the city of Sendai, made a stop at Acapulco after he crossed the Pacific Ocean on his way to Rome.[2]
