The planet was discovered by TESS, NASA's planet-hunting space telescope designed to find exoplanets that pass between us and their home star, by detecting the telltale dimming as the planet blocks a small percentage of the star's light.

这颗行星是由美国航空航天局的行星猎手太空望远镜TESS发现的。TESS的使命是通过检测行星阻隔恒星一小部分光线时指示性的变暗来寻找系外行星。
