Stephenson 2-18, A Red HyperSuper Giant Star, is not around three thousand in 200 dregres, It is much hotter that three thousand degres, It is over 10, 000 dreges, reaching to its full estimate temperature on its surface. Stephenson 2-18, A Red HyperSuper Giant Star, Its surface feels much hotter than our Sun, if we touch it, the temperature surface, us estimated about 300, 200 drives Celcius, which makes it three times the temperature than our Sun

It seems there are some inaccuracies in your description of Stephenson 2-18 (St2-18). Let me clarify some key points about this star:

  1. Type: Stephenson 2-18 is classified as a red supergiant star, and it is one of the largest known stars in terms of volume.

  2. Temperature: The effective temperature of Stephenson 2-18 is not over 10,000 degrees Celsius; rather, it is around 3,000 to 4,000 Kelvin (approximately 2,700 to 3,700 degrees Celsius), which is actually cooler than the Sun, whose surface temperature is about 5,500 degrees Celsius.

  3. Size and Luminosity: Stephenson 2-18 is noted for its immense size, with a radius estimated to be around 2,150 times that of the Sun. This large size contributes to its high luminosity, but its temperature is generally lower than that of our Sun.

  4. Comparison with the Sun: When comparing temperatures, it is important to note that Stephenson 2-18 is not three times hotter than the Sun but rather is cooler than the Sun.

In summary, Stephenson 2-18 is a fascinating star due to its size and characteristics, but it doesn't have the extreme temperature you mentioned. If you have more questions about this star or need further information, feel free to ask!
