HD 86226 b
HD 86226 b is a gas giant exoplanet discovered by the Magellan Planet Search Program in 2010.[1] It was confirmed in data collected by the CORALIE spectrograph on the Swiss 1.2-metre Leonhard Euler Telescope in 2012.[2] It takes about 4.6 years to orbit its G-type star and has a minimal mass of 0.92 Jupiters.[3]
