HD 104555

HD 104555 is a yellow dwarf star located approximately 83 light-years away from Earth in the constellation Crater. It is a G3V star, indicating it is a main-sequence star similar to our Sun in terms of temperature and luminosity, although it is slightly less massive and less luminous.

The star is of particular interest due to the discovery of a confirmed exoplanet, HD 104555 b, orbiting it. This planet is a gas giant with a mass similar to that of Jupiter, making it a hot Jupiter due to its proximity to the star and consequent high orbital temperature.

The discovery of HD 104555 b has contributed to our understanding of planetary formation and migration. Studying the characteristics of this star system helps astronomers refine models of how planets form and evolve around stars with similar properties to our own Sun. Further research into HD 104555 and its exoplanet could provide valuable insights into the diversity and prevalence of planetary systems throughout the galaxy. The star is visible with binoculars or a small telescope under good observing conditions.
