| With Kochab, Pherkad is one of the two northern stars known as the
Guardians of the Pole. Pherkad is a pulsing white
star (of the Delta Scuti group of variables) nearly five
hundred light years from the Solar System. Nearby in
the sky is a fainter star known as Pherkad Minor, but this is in fact quite unrelated to Pherkad itself.
