Comet Halley (1P/Halley)
Comet Halley (1P/Halley) is currently in the constellation of Hydra. The current Right Ascension of Comet Halley (1P/Halley) is 08h 24m 49s and the Declination is +02° 31’ 27” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current estimated magnitude of Comet Halley (1P/Halley) is 25.62 (JPL).
Summary of key facts about Comet Halley (1P/Halley) [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]:
- Halley's Comet is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the South-West direction at an altitude of 30° above the horizon.
- Given its current magnitude, Halley's Comet is visible only through long exposure photography.

Comet Halley (1P/Halley) Distance from Earth
The distance of Comet Halley (1P/Halley) from Earth is currently 5,324,419,916 kilometers, equivalent to 35.591549 Astronomical Units. Light takes 4 hours, 56 minutes and 0.3531 seconds to travel from Comet Halley (1P/Halley) and arrive to us.
The following chart shows the distance of Comet Halley (1P/Halley) 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 Halley's Comet from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Comet Halley (1P/Halley) to Earth
Between January 2013 and December 2100, the closest approach of Comet Halley (1P/Halley) to Earth happens on Fri Jul 29 2061 at a distance of 0.477990 Astronomical Units, or 71,506,301 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet Halley (1P/Halley) 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 Halley (1P/Halley), 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 Halley (1P/Halley) rise and set times
The rise and set times are defined as the time at which the upper limb of Comet Halley (1P/Halley) 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.
