How bright is Asteroid (NEO) 2014 YN?
The current visual magnitude of Asteroid (NEO) 2014 YN is 27.35. Given its brightness, Asteroid (NEO) 2014 YN 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 (NEO) 2014 YN, 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.
