How bright is Asteroid 2020 CD3 (Earth's minimoon)?

The current visual magnitude of Asteroid 2020 CD3 (Earth's minimoon) is 31.68. Given its brightness, Asteroid 2020 CD3 (Earth's minimoon) should be visible only through long exposure photography.


The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 2020 CD3 (Earth's minimoon), according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuracies for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies between the observed and predicted brightness because of their highly dynamic behaviour.
