HD 219617

HD 219617 is a star located in the constellation Pegasus. It is a relatively faint star, not easily visible to the naked eye. HD 219617 is a G-type main-sequence star, similar to our Sun, but potentially slightly less massive.

The star is of particular interest to astronomers because it is known to host at least one extrasolar planet, designated HD 219617 b. This exoplanet was discovered through the radial velocity method, which detects subtle variations in the star's velocity caused by the gravitational pull of an orbiting planet.

Information regarding the exoplanet's exact characteristics, such as its mass, radius, and orbital period, can be found in astronomical databases and scientific publications. Continued observation of HD 219617 and its planetary system may yield further insights into the formation and evolution of planetary systems around Sun-like stars.
