In astronomy, 15768 is used as the numerical designation for a minor planet (asteroid) in the catalog of small Solar System bodies. Such designations are assigned sequentially as objects are confirmed, and the number itself serves as a persistent identifier within the vast collection of discovered bodies.

Beyond mathematics and astronomy, 15768 often appears as an arbitrary identifier in databases, inventories, or catalog systems. Like many integers, its primary value lies in its role as a stable label that can be mapped to data, measurements, or records in a wide range of disciplines.
