How bright is Asteroid (NEO) 2007 WA?
The current visual magnitude of Asteroid (NEO) 2007 WA is 26.67. Given its brightness, Asteroid (NEO) 2007 WA 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) 2007 WA, 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.
