Same issues there. Asteroid collisions would be creating dust which would be resulting in wavelength differentials. Said collisions would also result in heat which would result in a visible increase in the infrared - also not there. There's lots of other issues as well which led to its doubt even just using older data, but I think those alone sufficiently remove it from the picture.
