HD 212301 is a G-type main-sequence star located approximately 90 light-years (27 parsecs) away from the Solar System in the constellation Lacerta. It has an apparent magnitude of about 7.78, making it too faint to be seen with the naked eye but observable with binoculars or a small telescope.
The star is designated "HD" as it is included in the Henry Draper Catalogue, a comprehensive astronomical star catalogue compiled by Annie Jump Cannon and her colleagues at Harvard College Observatory.
Characteristics:
- Spectral Type: G8V (though some sources classify it as F8V or F9V, indicating a yellow-white to yellow main-sequence star)
- Apparent Magnitude: +7.78
- Distance: Approximately 90 light-years (27 parsecs)
- Constellation: Lacerta
Planetary System: HD 212301 is known to host at least one exoplanet, HD 212301 b. This planet was discovered using the radial velocity method, which detects the subtle wobble of a star caused by the gravitational pull of an orbiting planet.
- HD 212301 b: A gas giant with a minimum mass of approximately 2.2 Jupiter masses. It orbits its host star with a period of about 629 days (1.72 years) at an average distance of roughly 1.34 Astronomical Units (AU).
