The value of the distance of 2015 RR245 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 2015 RR245 to Earth will happen on Wednesday 14 January 2093 at a distance of 32.929176 Astronomical Units, or 4,926,134,667 kilometers:

Light Curve

The following chart shows the light curve of asteroid 2015 RR245, 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.
