HD 154972 is a star located in the constellation Scorpius. It is cataloged in the Henry Draper (HD) Catalogue, a comprehensive astronomical catalog of stars compiled at Harvard College Observatory, primarily known for providing the first large-scale spectral classifications.
Characteristics:
- Spectral Type: HD 154972 is classified as a G5V star, meaning it is a G-type main-sequence star. This places it in a similar category to our Sun (a G2V star), though it is slightly cooler and less massive than the Sun.
- Apparent Magnitude: The star has an apparent visual magnitude of approximately 7.23. This makes it too faint to be seen with the naked eye from most locations, but it is readily observable with binoculars or a small telescope.
- Distance: It is located approximately 215 light-years (or about 66 parsecs) from Earth.
- Temperature: Its effective surface temperature is estimated to be around 5,500 Kelvin.
- Luminosity and Mass: As a G5V star, its luminosity and mass are slightly less than those of the Sun, consistent with its spectral classification.
Observational Information: Due to its relatively faint magnitude, HD 154972 is primarily of interest to astronomers for its stellar properties rather than as a prominent naked-eye object. It serves as a data point in studies of stellar evolution, galactic structure, and the properties of G-type stars. As of current public data, no exoplanets have been confirmed orbiting HD 154972.
