Here's why:

* Star Color and Temperature: A star's color is directly related to its surface temperature.

* Red stars are the coolest.

* Yellow stars (like our Sun) are in the middle.

* Blue stars are the hottest.

* Our Sun's Temperature: The Sun has a surface temperature of about 5,500 degrees Celsius (9,932 degrees Fahrenheit).

* Red Dwarfs: Red dwarf stars are much cooler than our Sun, with surface temperatures ranging from about 2,400 to 3,500 degrees Celsius (4,352 to 6,332 degrees Fahrenheit).

So, while the Sun is a yellow star, it's still hotter than all red dwarf stars.
