Comet 398P/Boattini

Comet 398P/Boattini is currently in the constellation of Sagittarius.

The current Right Ascension of Comet 398P/Boattini is 17h 53m 02s and the Declination is -17° 58’ 46” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet 398P/Boattini is 26.42 (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 398P/Boattini Distance from Earth

The distance of Comet 398P/Boattini from Earth is currently 877,048,806 kilometers, equivalent to 5.862709 Astronomical Units. Light takes 48 minutes and 45.5199 seconds to travel from Comet 398P/Boattini and arrive to us.

The following chart shows the distance of Comet 398P/Boattini 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 398P/Boattini from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Comet 398P/Boattini to Earth

Between 1 January 2013 and 30 December 2100, the closest approach of Comet 398P/Boattini to Earth happens on Wed Dec 23 2020 at a distance of 0.375438 Astronomical Units, or 56,164,772 kilometers:

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

Comet 398P/Boattini Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 398P/Boattini, 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.
