How bright is Asteroid 1998 OR2?
The current visual magnitude of Asteroid 1998 OR2 is 21.66. Given its brightness, Asteroid 1998 OR2 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 1998 OR2, 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.
