Answer:

1449 K

Explanation:

The surface temperature of a star is related to its peak wavelength by Wien's displacement law:

[tex]T=\frac{b}{\lambda}[/tex]

where

T is the surface temperature

b is Wien's displacement constant

[tex]\lambda=2\cdot 10^{-6} m [/tex]

So the surface temperature of the star is

[tex]T=\frac{2.898 \cdot 10^{-3} Km}{2\cdot 10^{-6} m}=1449 K[/tex]
