Comet Encke (2P/Encke)
Comet 2P/Encke is a periodic comet that takes about 3.3 years to complete one orbit around the Sun. It was first discovered by Pierre Méchain on January 17, 1786, and was later independently rediscovered by Johann Franz Encke on November 2, 1818. The comet is named after Encke, who calculated its orbit and predicted its return in 1822. Comet 2P/Encke has a relatively short orbital period and its orbit is known for being influenced by the gravitational pull of Jupiter. It has an average distance from the Sun of about 2.2 astronomical units (AU) and an eccentricity of 0.85, which means its perihelion distance is only 0.34 AU while its aphelion distance is around 3.5 AU. Comet 2P/Encke is known for being a source of the Taurid meteor shower, which occurs every year in late October and early November as Earth passes through the dust and debris left behind by the comet.
Comet Encke (2P/Encke) is currently in the constellation of Capricornus, at a distance of 459,088,993 kilometers from Earth.

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 Encke (2P/Encke) Distance from Earth
The distance of Comet Encke (2P/Encke) from Earth is currently 459,088,993 kilometers, equivalent to 3.068820 Astronomical Units. Light takes 25 minutes and 31.3560 seconds to travel from Comet Encke (2P/Encke) and arrive to us.
The following chart shows the distance of Comet Encke (2P/Encke) from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
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 2P/Encke from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet Encke (2P/Encke) to Earth
Between 1 January 1900 and 31 December 2099, the closest approach of Comet Encke (2P/Encke) to Earth happens on Sat Jul 5 1997 at a distance of 0.190257 Astronomical Units, or 28,462,061 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet Encke (2P/Encke) Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet Encke (2P/Encke), 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.
