195554

195554 is the numeric designation assigned to a specific minor planet in the solar system. In the system used by the IAU Minor Planet Center, a sequential number is given to a minor planet once its orbit is well determined, signaling that its trajectory can be predicted with confidence. Before receiving a number, such objects are identified by provisional designations that reflect the date of discovery. Some minor planets later receive official names, but many remain known by their number alone.

Discovery and identification details for 195554 are maintained by the Minor Planet Center. Typical entries include the discovery date, observing site, and the astronomers or survey team responsible for the initial observations. After discovery, follow-up observations are used to refine the orbit, enabling the assignment of a permanent number.

The orbital and physical characteristics of 195554 are described by its orbital elements, which determine its path around the Sun, including its semi-major axis, eccentricity, and inclination. Based on these elements, minor planets are categorized into dynamical classes, such as main-belt objects or other populations. Physical properties like diameter and albedo are often uncertain and can come from infrared surveys, occultations, or assumed values based on taxonomy. As with many numbered minor planets, detailed information is compiled in public databases and may be updated as new observations become available.

195554 is part of the broader catalog of hundreds of thousands of minor planets that help astronomers study the composition, formation, and evolution of the solar system. See also: Minor Planet Center, List of minor planets.
