Additional Information
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.
Rise and Set Times
Today's rise, transit and set times of Comet 129P/Shoemaker-Levy from Greenwich, UK (all times relative to the local timezone Europe/London):
- 129P/Shoemaker-Levy is above the horizon from Greenwich, UK.
- Right now it is placed in the South-South-East direction at an altitude of 20.29° above the horizon.
- Given its current magnitude, 129P/Shoemaker-Levy is visible only through long exposure photography.

Distance from Earth
The distance of Comet 129P/Shoemaker-Levy from Earth is currently
The following chart shows the distance of Comet 129P/Shoemaker-Levy 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 129P/Shoemaker-Levy from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach
Between 1 January 2000 and 31 December 2099, the closest approach of Comet 129P/Shoemaker-Levy to Earth happens on Fri Dec 24 2004 at a distance of 1.946997 Astronomical Units, or 291,266,666 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 129P/Shoemaker-Levy, 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.
