The system of longitude/latitude was developed and is used for the purpose of locating points on the Earth's surface. Rigel is a star, and its location is described by means of a similar but separate system of coordinates that applies to the 'celestial sphere'. Even if you want to talk about the point on Earth that Rigel is directly over, that point changes about every 30 seconds, and it sweeps completely around the Earth in a day.
There is more than one star in the Rigel "system". The main star, in terms of brightness, is Rigel A. That has a surface temperature of about 12,000 degrees Celsius.
