HD 222237

HD 222237 is a star located in the constellation Tucana. It is a Sun-like star, also classified as a G5V star, which indicates it is a yellow dwarf main-sequence star. This means it is fusing hydrogen into helium in its core, similar to our Sun, although with slightly different properties.

The star's apparent magnitude is around 7.5, meaning it is not visible to the naked eye. It requires binoculars or a telescope for observation. HD 222237 is part of the Hipparcos catalog, a comprehensive catalog of star positions and proper motions.

Its designation, "HD," refers to the Henry Draper Catalogue, a large astronomical catalog that includes spectral classifications for a vast number of stars. The number following "HD" is a unique identifier within that catalog.

Further studies have explored the properties of HD 222237, including its effective temperature, luminosity, and metallicity, contributing to a better understanding of stellar evolution and the characteristics of Sun-like stars. It has been considered as a potential target in exoplanet searches due to its similarities to our Sun.
