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 51P/Harrington Distance from Earth
The distance of Comet 51P/Harrington from Earth is currently 691,846,979 kilometers, equivalent to 4.624711 Astronomical Units. Light takes 38 minutes and 27.7531 seconds to travel from Comet 51P/Harrington and arrive to us.
The following chart shows the distance of Comet 51P/Harrington 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 51P/Harrington from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet 51P/Harrington to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Comet 51P/Harrington to Earth happens on Mon Sep 5 2022 at a distance of 0.719952 Astronomical Units, or 107,703,295 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 51P/Harrington Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 51P/Harrington, 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.
