It is not the brightest star in the sky, as many people think. It's important because it marks, roughly, the "North Pole of the sky".
Because it lets us navigate without GPS.
yes
Polaris, the same people who make the snowmobiles
Yes, it is very important to observers in the North Hemisphere. Great telescopes still align themselves with Polaris. Many amateurs, including myself, align their scopes with Polaris. This is know as polar alignment. It's to this day one of the most accurate forms of alignment.
It appears to remain stationary above the North Pole and that is why it is important.
PS-4 is the "Polaris" brand. Most people use 0-W40 as per most of the internet ATV forums out there.
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").
