Determination of temperatures of space objects – This method is based on finding the wavelength in the electromagnetic radiation spectrum of a space object that emits the maximum power. The body emits as a completely black body, which is quite normal for stars, and if we take into account that the radiation of an object has a wavelength in the range from maximum to minimum, then Wien’s law unambiguously connects the temperature of the body with the wavelength of the maximum radiation in its spectrum.
