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 19 Fortuna 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, 1900 and December 31, 2099, the closest approach of asteroid 19 Fortuna to Earth happened on Friday 15 October 1982 at a distance of 1.062725 Astronomical Units, or 158,981,460 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 19 Fortuna, 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.
