(85182) 1991 AQ

(85182) 1991 AQ is a minor planet, also known as a small solar system body. The designation "(85182)" indicates the object's permanent number in the catalog of minor planets, assigned after its orbit has been sufficiently well-determined. "1991 AQ" is the provisional designation assigned to the object upon its discovery. The "1991" indicates the year of discovery, and the "AQ" represents the specific half-month and sequence within that half-month when the discovery was made, according to the International Astronomical Union's minor planet designation scheme. This system is used to provide a temporary label to an object before it receives a permanent number.

This designation reveals that the object was discovered in the year 1991. The letter "A" indicates that it was discovered in the first half of January (January 1-15). The letter "Q" signifies the specific sequence of discoveries made during that particular half-month. Further observation is necessary to refine the orbit and physical characteristics of such objects, and eventually lead to a more descriptive or thematic naming.

The object is tracked by astronomers to understand its orbital path, which is crucial for assessing potential collision risks with Earth, although most minor planets pose no immediate threat. The study of these objects contributes to our understanding of the formation and evolution of the solar system.
