101605

101605 is the numerical designation assigned to a small body in the Solar System categorized as a minor planet, commonly referred to as an asteroid. The designation is issued by the Minor Planet Center (MPC) and indicates that it is the 101,605th minor planet to have its orbit sufficiently well determined for cataloging.

Minor planets begin with a provisional designation upon discovery, such as a year and alphanumeric code. After observations span enough to secure an orbit, the object receives a permanent number. Some numbered objects also receive a name chosen by their discoverers and approved by the International Astronomical Union; many remain unnamed.

Most numbered minor planets orbit in the main asteroid belt between Mars and Jupiter, but they can belong to various dynamical groups. The precise orbital elements and any available physical characteristics of 101605—such as position, orbit shape, size, and reflectivity—are maintained by the MPC and published in public databases. For current details, researchers consult the MPC or related astronomical catalogs.

As a catalog entry, 101605 serves primarily as a reference in scientific literature and observation planning. Its significance lies in its role within the broader inventory of small Solar System bodies rather than in any individual distinguishing attributes unless a name or notable characteristics have been assigned.
