' ధ్రువ నక్షత్రం ' ను ఇంగ్లీష్ లో ఏమంటారు?

Pole star : ధ్రువ నక్షత్రం.  

A pole star is a visible star, preferably a prominent one, that is approximately
aligned with the Earth's axis of rotation; that is, a star whose apparent position
is close to one of the celestial poles, and which lies approximately directly
overhead when viewed from the Earth's North Pole or South Pole.
