673685

673685 is a numeric identifier that appears in a variety of cataloging systems, databases, and scientific registries. In astronomy, it is used as a provisional designation in the Minor Planet Center database, identifying a specific asteroid discovered by a survey program in the early 21st century. The asteroid is characterized by its orbital elements, with a semi‑major axis of approximately 2.4 astronomical units and an estimated diameter of 7 kilometers. Its spectral type, determined from photometric observations, suggests it belongs to the carbonaceous C‑class, implying a primitive composition typical of objects formed in the outer regions of the protoplanetary disk.

In the field of biology, the same numeric string appears as the accession number of a gene sequence in GenBank. The gene encodes a protein involved in fungal cell wall synthesis and is conserved across several Aspergillus species. Researchers frequently reference NC_016818.1 when discussing antifungal drug development.

The identifier also functions as a product code in the electronics industry, where it is assigned to a specific model of a power supply unit. The unit, rated at 500 watts, is manufactured by a Taiwan-based supplier and is commonly used in high-performance computing rigs.

Because the same number is employed in disparate contexts, it is crucial for data integration projects to rely on full context information—such as database name, subject area, or associated metadata—to avoid ambiguity when linking records that share the numeric value 673685.
