Comet 319P/Catalina-McNaught Distance from Earth
The distance of Comet 319P/Catalina-McNaught from Earth is currently 575,204,725 kilometers, equivalent to 3.845006 Astronomical Units. Light takes 31 minutes and 58.6764 seconds to travel from Comet 319P/Catalina-McNaught and arrive to us.
The following chart shows the distance of Comet 319P/Catalina-McNaught 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 319P/Catalina-McNaught from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet 319P/Catalina-McNaught to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Comet 319P/Catalina-McNaught to Earth happens on Wed Jul 18 2068 at a distance of 0.175307 Astronomical Units, or 26,225,598 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 319P/Catalina-McNaught Brightness
The current visual magnitude of Comet 319P/Catalina-McNaught is 24.93.
The observed magnitude and coma diameter values are derived from the Comet Observers Database by averaging the values reported in recent observations (more recent than 4 days), when available. The Estimated Magnitude comes from the JPL Horizons ephemerides service and might be inaccurate given the highly dynamic and unpredictable behavior of comets. When available, please refer to the Observed Magnitude value and consider the Estimated 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 following chart is the predicted light curve (visual magnitude as a function of time) of Comet 319P/Catalina-McNaught, 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.
