| Discovery site | Xinglong Station Xinglong Station (NAOC) Xinglong Station is an observatory situated south of the main peak of the Yanshan mountains in Hebei province, China. Installed are seven telescopes: a Mark-III photoelectric astrolabe; a 60cm reflector; an 85cm reflector; a 60/90cm Schmidt telescope; an 1.26m infrared telescope; and a 2.16m... |

| Longitude of the ascending node Longitude of the ascending node The longitude of the ascending node is one of the orbital elements used to specify the orbit of an object in space. It is the angle from a reference direction, called the origin of longitude, to the direction of the ascending node, measured in a reference plane... (Ω) |

29552 Chern is a minor planet
Minor planet
An asteroid group or minor-planet group is a population of minor planets that have a share broadly similar orbits. Members are generally unrelated to each other, unlike in an asteroid family, which often results from the break-up of a single asteroid...
