How bright is Asteroid 9 Metis?
The current visual magnitude of Asteroid 9 Metis is 11.11. Given its brightness, Asteroid 9 Metis should be visible with the help of a binocular with a 70-80mm aperture or a small telescope.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 9 Metis, 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.
