How bright is Asteroid 20 Massalia?
The current visual magnitude of Asteroid 20 Massalia is 10.32. Given its brightness, Asteroid 20 Massalia should be visible with the help of a binocular with a 60mm aperture, might require a small telescope.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 20 Massalia, 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.
