HD 38801 b is an extrasolar, gas giant planet located in the constellation of Orion[1] whose discovery was announced in 2009 and was made using the radial velocity method.[2] The object, with a mass roughly 12 times that of Jupiter,[2] is located 324 light years (99.4 parsecs) from Earth[3][4] orbiting 1.65 astronomical units from its G-type star, HD 38801.[2][5] HD 38801 b, besides being the only planet in its system[3] also lies within the inner habitable zone[4] and takes around 1.9 years, or 693.5 days to complete a full orbit.[2]
Low Eccentricity
Hd 38801 b is characterized by its uniquely low eccentricity values, or having a near circular orbit. As a super massive planet with an orbital period of hundreds of days, this occurrence is quite uncommon.[6]
