Template:Short description Script error: No such module "infobox".Script error: No such module "Check for unknown parameters". HD 142022 Ab is an exoplanet discovered by the radial velocity method by Eggenberger et al. in 2005, after finding that HD 142022 A is wobbling which indicated the presence of a massive planet, with a minimum mass 4.5 times Jupiter. It has a relatively wide separation between the planet and the star of nearly 3 AU, and takes 1928 days or 5.28 years to revolve. As is common for long-period planets, it has a relatively high eccentricity of 53±20%.[1] In 2023, the inclination and true mass of HD 142022 Ab were determined via astrometry.[2]
