HD 145457

HD 145457 is a designation in the Henry Draper Catalogue, a comprehensive stellar catalog published between 1918 and 1924. The catalog lists stars primarily by their approximate position in the sky at the time of observation, making it a valuable resource for astronomers.

The specific object designated HD 145457 is a star. Like all entries in the Henry Draper Catalogue, the designation serves as a unique identifier for this particular star, allowing astronomers to differentiate it from other celestial objects. The catalog provides information about the star's position, brightness (magnitude), and spectral type.

Further research using the HD 145457 designation in modern astronomical databases and catalogs can reveal more detailed information about the star, such as its distance, temperature, age, and whether it possesses any known companions (e.g., exoplanets). The Henry Draper Catalogue serves as a fundamental starting point for identifying and studying stars, and HD 145457 is one of the many stars within its extensive collection. The accuracy and completeness of the data in the Henry Draper Catalogue have been superseded by more modern catalogs and observational techniques. Therefore, current research should consult updated stellar databases.
