Comet 10P/Tempel
Comet 10P/Tempel (also known as Comet Tempel 2) is a periodic comet that orbits the Sun once every 5.4 years. It has an eccentric orbit that takes it from a perihelion distance of 1.4 astronomical units (AU) to an aphelion distance of 4.7 AU. It was first discovered by Wilhelm Tempel in France on July 4, 1873.
Comet 10P/Tempel is currently in the constellation of Leo.
The current Right Ascension of Comet 10P/Tempel is 09h 54m 23s and the Declination is +16° 39’ 23” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current estimated magnitude of Comet 10P/Tempel is 20.98 (JPL).
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.

Comet 10P/Tempel Distance from Earth
The distance of Comet 10P/Tempel from Earth is currently 638,355,695 kilometers, equivalent to 4.267144 Astronomical Units. Light takes 35 minutes and 29.3254 seconds to travel from Comet 10P/Tempel and arrive to us.
The following chart shows the distance of Comet 10P/Tempel 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 10P/Tempel from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet 10P/Tempel to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Comet 10P/Tempel to Earth happens on Tue Aug 4 2026 at a distance of 0.414485 Astronomical Units, or 62,006,140 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 10P/Tempel Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 10P/Tempel, 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.
