Comet 7P/Pons-Winnecke is a short-period comet with an orbital period of 6.3 years. It was first discovered by Jean-Louis Pons on 12 June 1819 and rediscovered later by Friedrich August Theodor Winnecke on 9 March 1858. The comet has a perihelion distance of about 1.2 astronomical units and an aphelion distance of about 5.6 astronomical units.

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.

Comet 7P/Pons-Winnecke Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 7P/Pons-Winnecke, 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.
