We developed a statistical model for the asteroid component of the far-infrared sky for wavelengths ≤≤{5 μm}{λ}{1000 μm} based on the Statistical Asteroid Model (Tedesco et al., 2005). Far-infrared fluxes of ˜1.9 million asteroids are used to calculate confusion noise values and expected asteroid counts for space IR instruments in operation or in the near future. Our results show that the confusion noise due to asteroids will not increase the detection threshold for most of the sky. However, there are specific areas near the ecliptic plane where the effect of asteroids can be comparable to the contribution of Galactic cirrus emission and of the extragalactic background.
