Comet 9P/Tempel 1
Comet 9P/Tempel 1 is currently in the constellation of Gemini. The current Right Ascension of Comet 9P/Tempel 1 is 07h 13m 35s and the Declination is +26° 55’ 23” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current estimated magnitude of Comet 9P/Tempel 1 is 22.00 (JPL).
Summary of key facts about Comet 9P/Tempel 1 [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]:
- 9P/Tempel 1 is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the East-North-East direction at an altitude of 14° above the horizon.
- Given its current magnitude, 9P/Tempel 1 is visible only through long exposure photography.

Comet 9P/Tempel 1 Distance from Earth
The distance of Comet 9P/Tempel 1 from Earth is currently 743,652,957 kilometers, equivalent to 4.971013 Astronomical Units. Light takes 41 minutes and 20.5593 seconds to travel from Comet 9P/Tempel 1 and arrive to us.
The following chart shows the distance of Comet 9P/Tempel 1 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 9P/Tempel 1 from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest approach of Comet 9P/Tempel 1 to Earth
Between January 2013 and December 2100 the closest approach of Comet 9P/Tempel 1 to Earth happens on Sat Jun 16 2040 at a distance of 0.94638097 Astronomical Units, or 141,576,578 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 9P/Tempel 1 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 9P/Tempel 1, 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 9P/Tempel 1 rise and set times
The rise and set times are defined as the time at which the upper limb of Comet 9P/Tempel 1 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.
