How bright is Asteroid 4 Vesta?
The current visual magnitude of Asteroid 4 Vesta is 8.15. Given its brightness, Asteroid 4 Vesta should be visible with the help of a binocular with a 30-40mm aperture, easy with a small telescope.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 4 Vesta, 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.
