HD 69142

HD 69142 is a G5V star located in the constellation Puppis. It is a Sun-like star, meaning it is broadly similar in mass, temperature, and luminosity to our own Sun. The star is relatively nearby, located approximately 83 light-years from Earth.

HD 69142 is of particular interest to astronomers due to the discovery of a hot Jupiter exoplanet orbiting it. This planet, designated HD 69142 b, is a gas giant with a mass significantly larger than Jupiter. It orbits its host star very closely, resulting in an extremely short orbital period and high surface temperature. This proximity classifies it as a "hot Jupiter."

The star's designation, HD 69142, comes from the Henry Draper Catalogue, a comprehensive astronomical catalog compiled in the early 20th century. The catalog lists stars based on their position and brightness, assigning them unique numerical identifiers.

Observations of HD 69142 and its exoplanet contribute to our understanding of planetary formation and the diversity of planetary systems beyond our own Solar System. The characteristics of hot Jupiters like HD 69142 b present challenges to traditional planet formation models, spurring further research and refinement of our understanding of these processes.
