There is an unconfirmed detection of another planet in the epsilon Eri system, also a giant planet (although less massive at 0.1 Jupiter masses) in a very distant (40 AU) orbit.

在epsilon eri星系中还有一颗未确认的行星，那是在非常远的轨道(40个天文单位)上的另一颗巨星(虽然不足木星质量的0.1倍)。

His calculations suggest Nemesis is between 3 to 5 times the mass of Jupiter, rather than the 13 Jupiter masses or greater that some scientists think is a necessary quality of a brown dwarf.

他的计算认为“复仇者”应该介于3 - 5倍木星质量，而不是某些科学家认为的13倍木星质量或者更大质量以达到形成褐矮星的必要质量。

Such a small M-dwarf star has long been ruled out by WISE data, since observers would surely have spotted an object larger than roughly five Jupiter masses.
