Infrared observations of a star show that it is most intense at a wavelength of 2000nm.What is the temperature of the star鈥檚 surface?T in Kelvins = 2.9 * 10^6 / lambda peak (lambda in nm) - Wien's law
so your star should have a temperature of about 1,400k which sounds like a star made in the classroom.What is the temperature of the star鈥檚 surface?Our Sun has a spectral class of G2V. G2 means that it has a surface temperature of approximately 5,780 K (5,510 掳C)
As for other stars, this temperature varies widely, depending on size, mass, ext. This can be figured using several methods. Here is a site that discusses the best methods for calculation.
