255260

255260 is a minor planet designation assigned by the Minor Planet Center (MPC). The number indicates that this object has had its orbit sufficiently well determined to be numbered, a status it receives after multiple oppositions and observations. Before numbering, it is given a provisional designation that encodes the year of discovery and sequence of discovery within that year. If the discoverers propose a name and it is approved by the International Astronomical Union, the object may be known by a formal name; otherwise it is referred to by its number and provisional designation.

Discovered by survey programs or individual observers, 255260 is cataloged with orbital parameters in databases maintained by the MPC and NASA's JPL Small-Body Database. The majority of numbered minor planets reside in the main asteroid belt between Mars and Jupiter, and their orbits generally have semi-major axes in the range of about 2.0 to 3.5 astronomical units, with modest eccentricities and inclinations. Specific values for 255260's orbit—such as its semi-major axis, eccentricity, inclination, and orbital period—are published in these catalogs and can change slightly as new observations refine the trajectory.

Physical characteristics of numbered minor planets vary widely. For many objects, diameter estimates depend on measured infrared albedo or assumed values based on the object's brightness. Unless a direct study is available, the size, composition, and rotation period of 255260 remain uncertain.
