Comet C/2023 A3 (Tsuchinshan-ATLAS) | TheSkyLive (2024)

Comet C/2023 A3 (Tsuchinshan-ATLAS) is currently in the constellation of Leo,at a distance of 284,432,509 kilometers from Earth.The current Right Ascension of Comet C/2023 A3 (Tsuchinshan-ATLAS) is 11h 33m 39s and the Declination is +03° 00’ 45” (topocentric coordinatescomputed for the selected location: Greenwich, United Kingdom).The current estimated magnitude of Comet C/2023 A3 (Tsuchinshan-ATLAS) is 10.62 (JPL) while the latest observed magnitude is 11.5 (COBS).

Comet C/2023 A3 (Tsuchinshan-ATLAS) was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) on 22 February 2023 and it was also independently observed few weeks before in January 2023 at the Tsuchinshan Chinese Observatory (Purple Mountain Observatory of the Chinese Academy of Sciences). The official designation includes both Tsuchinshan and ATLAS due to these independent observations.Its retrograde orbit, meaning it moves in the opposite direction to most major solar system objects, is parabolic-like with a perihelion distance of 0.39 astronomical units (AU).Comet C/2023 A3 (Tsuchinshan-ATLAS) is notable and actively observed because, based on current estimations, it is could become bright enough to be visible to the naked eye during its perihelion passage between September and October 2024.

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 Magnitudecomes from the JPL Horizons ephemerides service and, in the case of comets, might beinaccurate given the highly dynamic and unpredictablebehavior of these objects. When available, please refer to the Observed Magnitude value and consider the Predicted Magnitude as adirectional indication. We acknowledge with thanks the comet observations from the COBS Comet ObservationDatabase contributed by observers worldwide and used in this table toreport recent comet observations.

The distance of Comet C/2023 A3 (Tsuchinshan-ATLAS) from Earth is currently 284,432,509 kilometers,equivalent to 1.901314 Astronomical Units.Light takes15 minutes and 48.7647 seconds to travel from Comet C/2023 A3 (Tsuchinshan-ATLAS) and arrive to us.

The following chart shows the distance of Comet C/2023 A3 (Tsuchinshan-ATLAS) 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 A3 (Tsuchinshan-ATLAS) from Earth is also available as a real time updated value in theLive Position and Data Tracker.

Between 1 January 2000 and 31 December 2099,the closest approach ofComet C/2023 A3 (Tsuchinshan-ATLAS) to Earth happens on Sun Oct 13 2024 at a distance of 0.476126 Astronomical Units, or71,227,371 kilometers:

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

The following chart is the predicted light curve(visual magnitude as a function of time) of Comet C/2023 A3 (Tsuchinshan-ATLAS),according to the most recent ephemerides data. Magnitude data is sampled with a 2 days interval and there might be inaccuraciesfor objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepanciesbetween the observed and predicted brightness because of their highly dynamic behaviour.
