How bright is Asteroid 7 Iris?

The current visual magnitude of Asteroid 7 Iris is 9.97. Given its brightness, Asteroid 7 Iris 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 7 Iris, 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.
