2025年初,牛津大学团队确认了超地球HD 20794 d,这颗“超级类地行星”,其信号首次被捕捉于2022年。它绕一颗类太阳G型恒星运行,距地球仅20光年,质量约为地球的6倍,处于宜居带内,可能具备液态水条件。

与此同时,今年早些时候,研究人员在太阳系外发现了另一颗“超级地球”。据牛津大学的研究结果,这颗被命名为HD 20794 d的系外行星质量是地球的六倍,其表面可能存在液态水。它距离地球20光年,在一颗类似太阳的恒星的宜居带内运行。
这颗新发现的行星被命名为HD 20794 d,质量是地球的6倍,距离地球约20光年,围绕一颗类似太阳的恒星运行。 它的轨道位于该星系的宜居带内,这意味着它与恒星的距离合适,其表面能维持液态水存在,液态水是生命所需的一种关键成分。
