Asteroid (NEO) 2021 UX1 Brightness

The current visual magnitude of Asteroid (NEO) 2021 UX1 is 31.54.


The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2021 UX1, 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.
