The observed values of Magnitude, Coma Diameter and Tail Length are derived from the most recent observation recorded at the Comet Observers Database. The value of Predicted Magnitude comes from the JPL Horizons ephemerides service and, in the case of comets, might be inaccurate given the highly dynamic and unpredictable behavior of these objects. When available, please refer to the Observed Magnitude value and consider the Predicted Magnitude as a directional indication. We acknowledge with thanks the comet observations from the COBS Comet Observation Database contributed by observers worldwide and used in this table to report recent comet observations.

The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 19P/Borrelly from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Comet 19P/Borrelly to Earth

Between 1 January 2013 and 30 December 2100, the closest approach of Comet 19P/Borrelly to Earth happens on Wed Dec 6 2028 at a distance of 0.414136 Astronomical Units, or 61,953,874 kilometers:

Comet 19P/Borrelly Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 19P/Borrelly, 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.
