Polaris is in the constellation Small Bear (Ursa Minor). I didn't check whether it actually is the brightest star in that constellation.
No. The brightest star in the night sky is Sirius.

Polaris. It is a star, the others are constellations.
Polaris is the brightest star in the constellation Ursa Minor.
Polaris (North Star)
The North star is called Polaris. Polaris is the brightest star in the constellation Ursa Minor. It is not the brightest star in the night sky; that title goes to Sirius, in Canis Major. Polaris has 2 companion stars: Polaris AB and Polaris B. It's spectral type is F7 Ib-II SB.
Polaris is considered to be a very sanctification star is because it is closer to the north celestial pole. This is the brightest star in the earth's sky.
Constellations apparently
The North Star (Polaris) is the brightest star in the constellation Ursa Minor and the 45th brightest star in the night sky. Its temperature is 6015 K.
Circumpolar constellations means that a constellation orbits around the north star. Otherwise, polaris.
