Polaris is a Trinary star system, but there are many other trinary star systems out there, and to date no exo solar planets have been discovered around any of the stars that make up the Polaris system. Not to mention that Polaris A being a red giant and Polaris B and C being a close binary star system the existence of any planets is very unlikely.
Polaris is a multiple star system; each of the stars that make it up has its own surface temperature. For more details, I suggest you take a look at the Wikipedia article on "Polaris".
The name of the north star is Polaris. As the brightest star in the constellation of Ursa Minor it is also called alpha Ursae Minoris. It is actually a multiple star comprised of Polaris Aa, Polaris Ab and Polaris B.

Polaris is a star, and it doesn't revolve around any planets. It is possible that other planets revolve around Polaris, but so far I'm not aware that anyone has looked.
Polaris, also known as Alpha Ursae Minoris, will become the North Star again in 27,800 AD. The cycle takes about 25,770 years to complete. Polaris is the current North Star. Polaris replaced Thuban around the first millennium BC. It will become closest to the celestial north pole around the year 2100 and start moving farther away. Gamma Cephei, also known as Airai, will replace Polaris around 3000, followed by Iota Cephei in 5200. Polaris will again become the Pole star in 27.800 after it finishes the 25,770 year cycle.
No, Rigel is not the closest star to Polaris (the North Star). Rigel is a bright star in the constellation Orion, while Polaris is located in the constellation Ursa Minor. The closest star to Polaris is Urodelus, also known as "Polaris Australis."
The north star is polaris's other name.
Polaris is not a galaxy, it is a star.
The North Star, or Polaris. This star remains nearly stationary in the sky while all other stars seem to rotate around it due to the Earth's rotation on its axis.
Polaris and the North Star are the only two names I know.
