That means that, even if the planet has terrestrial moons, they likely wouldn't be able to stand the extreme temperature swings that go along with Epsilon Eridani b's eccentric orbit.

这意味着，即使这个星球有类似地球的卫星，它们也不可能承受得了天苑四b椭圆轨道带来的极端温度变化。

The orbit of the earth around the sun is eccentric because the orbit is slightly elliptical and so has effectively has two centres (neither of them the centre of the sun).

地球环绕太阳的公转轨道是偏心的，这是因为地球的公转轨道稍微呈椭圆形，所以这个轨道实际上就有两个中心（这两个中心都不与太阳的中心重合）。

Mercury's orbit is highly eccentric, meaning it's path is elliptical.

水星的轨道非常古怪，这意味着它的路径是椭圆形。

Comprised of silicate rock, the asteroid rolls through its eccentric orbit like a tumbling potato.

Curiosity was landing on Mars in an uneasy season, when the planet was swinging closer to the sun on its eccentric orbit, stirring up an already volatile climate.

The second piece of evidence pointing to is the eccentric orbit of an existing planet around the star, which is in an orbit not normally expected in this type of system.
