With the same composition as Earth, it would have a radius of 2.08 times that of the Earth. It orbits near the inner edge of the habitable zone of HD 20781.Шаблон:Citation needed
This planet was initially reported in a 2011 preprint, which referred to it as HD 20781 c.[3] However, the 2017 paper (published in a journal in 2019) that confirmed the planet designated it HD 20781 e, using the c designation for a different, shorter-period planet.[1]
