Transcript for scene 32 of the video " The Incredible Experience vs Ice Age - part 2" by Rolf Witzsche  

Rigel is nearly 80-times larger than the Sun

The giant star Rigel is nearly 80-times larger than the Sun and has an estimated surface temperature of 12,000 degrees, located at a distance of 880 light years from us. Rigel proves that giant stars can be highly active stars if the plasma density exists. For Rigel, there might not be enough of it. A fully active star of its size would have a surface temperature of 50,000 to 60,000 degrees.
