Comet C/2023 A1 (Leonard)
The current Right Ascension of Comet C/2023 A1 (Leonard) is 08h 26m 21s and the Declination is -58° 45’ 40” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current estimated magnitude of Comet C/2023 A1 (Leonard) is 22.75 (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.
- C/2023 A1 (Leonard) is below the horizon from Greenwich, United Kingdom .

The distance of Comet C/2023 A1 (Leonard) from Earth is currently 521,180,239 kilometers, equivalent to 3.483875 Astronomical Units. Light takes 28 minutes and 58.4701 seconds to travel from Comet C/2023 A1 (Leonard) and arrive to us.
The following chart shows the distance of Comet C/2023 A1 (Leonard) 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 C/2023 A1 (Leonard) from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet C/2023 A1 (Leonard) to Earth
Between 1 January 2014 and 31 December 2099, the closest approach of Comet C/2023 A1 (Leonard) to Earth happens on Thu Mar 2 2023 at a distance of 1.186987 Astronomical Units, or 177,570,761 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet C/2023 A1 (Leonard) Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet C/2023 A1 (Leonard), 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.
