Nice.<p>I wonder if the daytime brightness would really be that impressive? I guess they have a lot higher albedo than the moon, but the moon is barely visible during the day.<p>Also, they wouldn't be visible all night most of the time, because they'd be shaded by the Earth. But at night they would probably be bright enough that it would be difficult to see stars. A lot brighter than the full moon, for sure.<p>The lack of stars may even have prevented the development of astronomy, and for sure it would be a big headache for astronomers! Maybe having observatories exactly on the equator would work, but otherwise it would be very difficult to see anything faint due to the glare.
