HD 212301 b is an extrasolar planet located approximately 172 light-years away in the constellation of Octans, orbiting the star HD 212301. This is a low-mass exoplanet with a mass class of III (sub-Jupiter) and an appearance class of L (Alkali metal giant). It has an orbital period of 2.25 Earth days with the angular separation of 0.65 Milliarcsecond. The orbital distance is 0.0341 astronomical units or 5.10 gigameters or 0.165 microparsecs.

dbpprop:abstract
  • HD 212301 b is an extrasolar planet located approximately 172 light-years away in the constellation of Octans, orbiting the star HD 212301. This is a low-mass exoplanet with a mass class of III (sub-Jupiter) and an appearance class of L (Alkali metal giant). It has an orbital period of 2.25 Earth days with the angular separation of 0.65 Milliarcsecond. The orbital distance is 0.0341 astronomical units or 5.10 gigameters or 0.165 microparsecs. The periastron and apastron distance are identical to average orbital distance, meaning its eccentricity is 0.0%. The longitude of periastron is close to 0° or 360°. The time of periastron is 2,453,549.195 JD. The average orbital speed of this planet is as fast as 165.8 km/s. The semi-amplitude or the speed of the stellar wobble caused by a planet is 59.5 m/s. On August 22, 2005, taking place in ESO La Silla Observatory in Chile, the planet was discovered by Lo Curto who used the HARPS spectrometer.
  • HD 212301 b ist ein Exoplanet, der den gelben Zwerg HD 212301 alle 2,24572 Tage umkreist. Auf Grund seiner hohen Masse wird angenommen, dass es sich um einen Gasplaneten handelt.
