HD 38801 b
Jovian size planet orbiting HD 38801
HD 38801 b is an extrasolar, gas giant planet located in the constellation of Orion[3] whose discovery was announced in 2009 and was made using the radial velocity method.[4] The object, with a mass roughly 12 times that of Jupiter,[4] is located 324 light years (99.4 parsecs) from Earth[5][6] orbiting 1.65 astronomical units from its G-type star, HD 38801.[4][7] HD 38801 b, besides being the only planet in its system[5] also lies within the inner habitable zone[6] and takes around 1.9 years, or 693.5 days to complete a full orbit.[4]
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.[1]
