I would say because of its temperature:
Explanation:
A hot object emits radiation but the wavelength of this radiation depends upon its temperature:
The peak of emission is centred around the visible/IR part of the EM spectrum.
Consider a hot piece of Iron; you'll see becoming red corresponding to a certain specific temperature of the metal!
You can have a look at Planck's description of Black Body Radiation as well.
