The value of the distance of 2013 RF98 from Earth is also available as a real time updated value in the live position tracker.

Closest Approach to Earth

In the period between January 1, 2000 and December 31, 2099, the closest approach of asteroid 2013 RF98 to Earth happened on Friday 16 October 2009 at a distance of 35.187488 Astronomical Units, or 5,263,973,361 kilometers:

Light Curve

The following chart shows the light curve of asteroid 2013 RF98, i.e., its apparent magnitude as a function of time. The curve is calculated using the latest ephemerides provided by JPL Horizons. The magnitude data is sampled with the interval of 2 days. Because of this sampling, inaccuracies may occur for objects that have large variations of brightness over a few days. For comets, large discrepancies can arise between the calculated brightness and the observations due to their highly dynamic, and not always precisely predictable, behavior.
