A left-mouse-click on any object in the star map brings up an information box:
The top line of text is the star's proper name, if it has one.
Below this is the Bayer designation and, at the bottom, the
apparent magnitude or brightness of the star.
In this case the star was the Pole Star Polaris which is star Alpha in the constellation of Ursa Minor.
It is fairly bright having a visual magnitude of 2.02.
Bayer letters:
These are Greek letters used to label the brightest stars in a constellation. Typically, but not always, the letters are in order of brightness or magnitude so, for example, the star 'Alpheratz' - the brightest star in Andromeda - is known as alpha
Andromedae.
Magnitude:
The apparent magnitude 'm' of a star is a measure of how bright it appears when viewed from earth. The smaller the value of 'm' the brighter the star; very bright objects have negative magnitudes.
Sirius, the brightest star in the sky, has a magnitude -1.5 and the faintest object which can be seen with the naked eye in rare, perfect conditions has a magnitude of about +6.5
Unfortunately, if you live in a city, the effect of light pollution means that you will be unlikely to see stars fainter than about m=3.5
