I said the information is the positions of visible stars in the sky. The function of this information, for many thousands of years, was navigation (latitude and direction), time-telling (seasons), and storytelling (constellations). Any change that would impact navigation, time-telling, or storytelling, or create a visual difference would impact one or all these things.
There are about 9,000 visible stars in the sky (low estimate). Keeping things like visual acuity in mind (Naked eye - Wikipedia), we can compute the information. However, even if there are just two possible locations in the sky for every star (absurd) and only half the stars are important (absurd), we are still at 4,500 bits of information in the position of stars in the sky. That does not even tell us the region of sky we are looking at (determined by season and latitude), but we can neglect this for now.
