Comet SWAN (C/2020 F8)

Comet SWAN (C/2020 F8) is currently in the constellation of Eridanus.

The current Right Ascension of Comet SWAN (C/2020 F8) is 04h 25m 41s and the Declination is -25° 19’ 37” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet SWAN (C/2020 F8) is 21.91 (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 SWAN (C/2020 F8) Distance from Earth

The distance of Comet SWAN (C/2020 F8) from Earth is currently 1,771,852,407 kilometers, equivalent to 11.844102 Astronomical Units. Light takes 1 hours, 38 minutes and 30.2634 seconds to travel from Comet SWAN (C/2020 F8) and arrive to us.

The following chart shows the distance of Comet SWAN (C/2020 F8) 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/2020 F8 (SWAN) from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Comet SWAN (C/2020 F8) to Earth

Between 1 January 2013 and 30 December 2100, the closest approach of Comet SWAN (C/2020 F8) to Earth happens on Wed May 13 2020 at a distance of 0.555961 Astronomical Units, or 83,170,523 kilometers:

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

Comet SWAN (C/2020 F8) Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet SWAN (C/2020 F8), 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.
