HD 16175 b is anexoplanet located approximately 195.7light-years away in theconstellation ofAndromeda, orbiting thestarHD 16175. This planet has aminimum mass 4.8 times that ofJupiter; the true mass was initially unknown since theinclination of the orbit was unknown. This planet orbits at about 2.2astronomical units, taking 2.73 years to revolve around the star. Theorbit of the planet is highly elliptical with aneccentricity of 0.64.[3] In 2023, the inclination and true mass of HD 16175 b were determined viaastrometry.[2]
The planet HD 16175 b is namedAbol. The name was selected in theNameExoWorlds campaign byEthiopia, during the 100th anniversary of theIAU. Abol is the first of three rounds of coffee in the Ethiopian traditionalcoffee ceremony.[5][6]
The discovery was made usingradial velocity measurements taken between November 2004 and March 2009 with theCoudé Auxiliary andC. Donald Shane telescopes atLick Observatory.[1]
