Comet C/2021 D2 (ZTF)
Comet C/2021 D2 (ZTF) is currently in the constellation of Pyxis.
The current Right Ascension of Comet C/2021 D2 (ZTF) is 08h 34m 43s and the Declination is -28° 25’ 04” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current estimated magnitude of Comet C/2021 D2 (ZTF) is 21.05 (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 C/2021 D2 (ZTF) Distance from Earth
The distance of Comet C/2021 D2 (ZTF) from Earth is currently 952,608,510 kilometers, equivalent to 6.367795 Astronomical Units. Light takes 52 minutes and 57.5600 seconds to travel from Comet C/2021 D2 (ZTF) and arrive to us.
The following chart shows the distance of Comet C/2021 D2 (ZTF) 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/2021 D2 (ZTF) from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet C/2021 D2 (ZTF) to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Comet C/2021 D2 (ZTF) to Earth happens on Tue Feb 8 2022 at a distance of 2.536475 Astronomical Units, or 379,451,320 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet C/2021 D2 (ZTF) Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet C/2021 D2 (ZTF), 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.
