The distance of Asteroid (NEO) 2010 RA91 from Earth is currently
The following chart shows the distance of Asteroid (NEO) 2010 RA91 from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth.
Closest Approach
During the next 10 years, the closest approach of Asteroid (NEO) 2010 RA91 to Earth happens on Sun Mar 22 2026 at a distance of 0.012003 Astronomical Units, or 1,795,577 kilometers:
Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid (NEO) 2010 RA91, 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.
