naked-eye brightness

Currently this star is too faint to be visible with the naked eye, but over the next few months it will start climbing in brightness until it becomes one of the brightest stars in this constellation.

通常这颗恒星亮度非常微弱，因而不能用肉眼直接观察到，但是在接下来的几个月中，它的亮度将不断攀升，直到成为鲸鱼座中最明亮的恒星之一。

In the two days leading up to the full moon, the orb might look full to the naked eye, but its brightness is only half of what it will be on the night that the moon is full.

在满月以前的两个日子里，在白天也可用肉眼看到月亮这个球体的全部，但其亮度只有晚上满月的一半。
