HD 85622

HD 85622 is a G-type main-sequence star located in the constellation Hydra. It is approximately 90 light-years away from Earth. The star is slightly more massive and luminous than the Sun.

HD 85622 has been the subject of astronomical study, primarily focused on identifying and characterizing exoplanets orbiting it. As of October 2023, one exoplanet, HD 85622 b, has been confirmed to orbit the star.

Planetary System

HD 85622 b is a gas giant exoplanet with a mass of approximately 5.6 times that of Jupiter. It orbits HD 85622 at a distance of about 1.1 astronomical units (AU) with an orbital period of roughly 3.6 years. Its discovery was made using the radial velocity method, which detects subtle changes in a star's motion caused by the gravitational pull of an orbiting planet.

Stellar Characteristics

HD 85622 is a relatively Sun-like star, classified as a G8V star. This means it is a main-sequence star with a surface temperature and luminosity similar to the Sun, but slightly cooler. Its age is estimated to be several billion years. Further studies of the star's properties continue to contribute to our understanding of stellar evolution and planet formation.
