29981

29981 is a minor planet in the outer Solar System, located in the Kuiper belt, a region beyond Neptune's orbit. It was discovered on September 14, 2002, by astronomers at the Palomar Observatory in California. The object is classified as a cubewano, a group of Kuiper belt objects that do not exhibit significant orbital resonances with Neptune. 29981 has an estimated diameter of about 200 kilometers, making it one of the larger objects in the Kuiper belt. Its orbit is relatively stable, with an orbital period of approximately 290 Earth years. The surface of 29981 is believed to be composed of a mixture of ices and rocky materials, typical of Kuiper belt objects. Due to its distance and size, 29981 has not been extensively studied, and much about its composition and physical characteristics remains unknown. The object is named after the year of its discovery, 29981.
