Additional Information
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.

Distance from Earth
The distance of comet C/2014 UN271 (Bernardinelli-Bernstein) from Earth is currently
The following graph shows the distance of comet C/2014 UN271 (Bernardinelli-Bernstein) from Earth as a function of time. In the chart the distance is measured in Astronomical Units and the data is sampled with an interval of 1 day.
Note: The values in this chart may not be entirely accurate around the time of closest approach for objects passing very close to Earth at high speed (e.g., Near-Earth Objects).
The value of the distance of C/2014 UN271 (Bernardinelli-Bernstein) from Earth is also available as a real time updated value in the live position tracker.
Closest Approach to Earth
In the period between January 1, 2013 and December 30, 2100, the closest approach of comet C/2014 UN271 (Bernardinelli-Bernstein) to Earth will happen on Saturday 5 April 2031 at a distance of 10.110524 Astronomical Units, or 1,512,512,813 kilometers:
Note: the values for the closest approach are computed with a sampling interval of 1 day.
Light Curve
The following chart shows the light curve of comet C/2014 UN271 (Bernardinelli-Bernstein), i.e., its apparent magnitude as a function of time. The curve is calculated using the latest ephemerides provided by JPL Horizons. The magnitude data is sampled with the interval of 2 days. Because of this sampling, inaccuracies may occur for objects that have large variations of brightness over a few days. For comets, large discrepancies can arise between the calculated brightness and the observations due to their highly dynamic, and not always precisely predictable, behavior.
