Narrative:

On approach to 28C at ord. Cleared for the approach at 4000 ft over hazil. First officer was pilot flying. Just as the descent was started on the glideslope over the shoreline of lake michigan; I saw a drone below and to the left side of the nose of the airplane pass underneath. My best guess on the altitude is 2000-3000 ft. It was close enough to my aircraft that I could see 2 white propellers on the top. The body appeared to be orange in color. It was only in sight for a couple of seconds before passing underneath the nose. I reported the sighting to ATC.
