Closest Approach
During the next 10 years, the closest approach of Asteroid (NEO) 2021 RO16 to Earth happens on Sat Apr 22 2034 at a distance of 0.004919 Astronomical Units, or 735,940 kilometers:
Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2021 RO16, 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.
