Comet C/2023 X2 (Lemmon)

Comet C/2023 X2 (Lemmon) is currently in the constellation of Taurus, at a distance of 1,150,433,812 kilometers from Earth.

The current Right Ascension of Comet C/2023 X2 (Lemmon) is 04h 02m 59s and the Declination is +24° 37’ 31” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet C/2023 X2 (Lemmon) is 20.38 (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.

The distance of Comet C/2023 X2 (Lemmon) from Earth is currently 1,150,433,812 kilometers, equivalent to 7.690175 Astronomical Units. Light takes 1 hours, 3 minutes and 57.4341 seconds to travel from Comet C/2023 X2 (Lemmon) and arrive to us.

The following chart shows the distance of Comet C/2023 X2 (Lemmon) 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 X2 (Lemmon) from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Comet C/2023 X2 (Lemmon) to Earth

Between 1 January 2000 and 31 December 2099, the closest approach of Comet C/2023 X2 (Lemmon) to Earth happens on Thu Dec 11 2025 at a distance of 4.685871 Astronomical Units, or 700,996,300 kilometers:

NOTE: values for the closest approach are computed with a sampling interval of 1 day.

Comet C/2023 X2 (Lemmon) Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet C/2023 X2 (Lemmon), 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.
