Epsilon Tauri b ( Amateru ) is an exoplanet that orbits the red giant Epsilon Tauri with an orbital period of 594.9 days. The planet was discovered in 2007 by Sato et al. discovered using the radial velocity method. Its minimum mass is more than 7 M J , which makes it one of the so-called Super Jupiters .
In addition to its systematic name Epsilon Tauri b, the property was given the proper name Amaterasu after the Japanese sun deity of the same name after a public IAU competition on December 15, 2015 . The name was shortened to avoid confusion with the main belt asteroid (10385) Amaterasu .
