Features
A star radiates a huge amount of energy. It is assumed that it is surrounded by a giant cloud of dust [9] . V602 Kiel is located from the Sun at a distance of 6524 St. years old . The temperature is 3432 K. The mass of the star is about 18 solar . It shines brighter than the Sun more than 100 thousand times, and the radius is 1050 solar , which allows us to attribute this star to the largest of the known .
