    I do not have their exact dimensions but photos on in this Spaceflight Nom
    article show that they are significantly smaller than the 0.94 m diameter
    Starshine 3:
    My guess is that their standard magnitudes will be magnitude 8 (1000 km, 90 deg
    phase angle) or fainter, so they are likely to be difficult to see even using
    binoculars. Of course, the only way to be certain is to try to observe them.
