Comet 12P/Pons-Brooks is currently in the constellation of Hercules. The current Right Ascension of Comet 12P/Pons-Brooks is 18h 03m 30s and the Declination is +19° 10’ 50” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current estimated magnitude of Comet 12P/Pons-Brooks is 23.91 (JPL).
Summary of key facts about Comet 12P/Pons-Brooks [tip: you can also create a Quick Access page for this data if you access it frequently and would like to have a simpler view]:

Comet 12P/Pons-Brooks Distance from Earth
The distance of Comet 12P/Pons-Brooks from Earth is currently 1,395,655,364 kilometers, equivalent to 9.329380 Astronomical Units. Light takes 1 hours, 17 minutes and 35.4052 seconds to travel from Comet 12P/Pons-Brooks and arrive to us.
The following chart shows the distance of Comet 12P/Pons-Brooks 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 12P/Pons-Brooks from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Comet 12P/Pons-Brooks to Earth
Between January 2013 and December 2100, the closest approach of Comet 12P/Pons-Brooks to Earth happens on Sun Aug 28 2095 at a distance of 1.525129 Astronomical Units, or 228,156,023 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 12P/Pons-Brooks brightness
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 12P/Pons-Brooks, 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.
Comet 12P/Pons-Brooks rise and set times
The rise and set times are defined as the time at which the upper limb of Comet 12P/Pons-Brooks touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
