HD 77361 is a catalog identifier from the Henry Draper Catalogue, a comprehensive list of stellar spectra compiled in the early 20th century. The “HD” prefix denotes inclusion in this catalogue, and the number 77361 serves solely as an entry index; it does not convey intrinsic physical characteristics of the star itself.
Because specific, reliably sourced details (such as spectral type, luminosity class, apparent magnitude, distance, or constellation location) are not readily available in widely recognized encyclopedic references, the entry cannot be described with verifiable astronomical data. Consequently, the term is not broadly recognized as a distinct object in mainstream astronomical literature beyond its presence as an HD catalog number.
Possible contextual usage
- In professional astronomy databases (e.g., SIMBAD, VizieR), “HD 77361” functions as a query key to retrieve any associated observational data that may exist for the corresponding star.
- In scholarly articles, the designation may appear when discussing samples of stars selected from the Henry Draper Catalogue for statistical analyses or surveys.
Etymology
- “HD” is an abbreviation of Henry Draper, honoring the American astronomer who initiated the photographic spectral survey of stars.
- The numeric component is simply sequential, reflecting the order in which entries were recorded during the catalogue’s compilation.
