| A prominent and relatively bright yellow-white star that belongs to one constellation and two asterisms.
It marks the centre of the Great Bear's back (its name means 'bear'), and is also the tip of the Plough's
share, and the northern of the two Pointers. It has a faint companion that orbits it every 44 years.
