Note: The values in this chart may not be entirely accurate around the time of closest approach for objects passing very close to Earth at high speed (e.g., Near-Earth Objects).

The value of the distance of 2015 TB145 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, 2013 and December 30, 2100, the closest approach of asteroid 2015 TB145 to Earth happened on Sunday 1 November 2015 at a distance of 0.006724 Astronomical Units, or 1,005,856 kilometers:

Note: the values for the closest approach are computed with a sampling interval of 1 day.

Light Curve

The following chart shows the light curve of asteroid 2015 TB145, 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.
