How many dealers does Polaris have?
That depends on the latitude from which you are observing Polaris. At the Equator (0 latitude) Polaris will be tangential to the northern horizon (0 degrees of altitude) At 52 degrees north the altitude of Polaris will be 52 degrees Therefore At the North Pole (90 latitude) Polaris will be overhead (90 degrees of altitude).
Parts for a Polaris Predator 500 can be found in a variety of stores, such as Kapsco Moto, but fully assembled ATVs may be harder to find. Some are available on eBay; otherwise, one will need to find a dealer. Websites ATV Shop Online and ATV both feature "find a dealer" functions, which can search for local dealers.
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.
No. Polaris is a multiple star system. In the late 18th century it was resolved into two components, Polaris A and Polaris B. Later, Polaris A was resolved further into Polaris Aa and Polaris Ab. Neither Polaris Aa nor Polaris Ab are red giants. Aa is a supergiant and Ab is a dwarf; both of them are spectral class F ("yellow-white").
Polaris is not a constellation but it is the brightest star in the constellation Ursa Minor, the Little Bear. Polaris is not a single star just like half of all known stars are not single stars like our sun but are normally in a system of two or more stars. Polaris is part of a system that is four stars. It's closest companion known as Polaris Ab is easy to see in a small telescope.
