Comet 185P/Petriew

Comet 185P/Petriew is currently in the constellation of Hydra. The current Right Ascension of Comet 185P/Petriew is 09h 18m 32s and the Declination is +05° 51’ 23” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet 185P/Petriew is 16.24 (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 185P/Petriew Distance from Earth

The distance of Comet 185P/Petriew from Earth is currently 297,654,787 kilometers, equivalent to 1.989699 Astronomical Units. Light takes 16 minutes and 32.8695 seconds to travel from Comet 185P/Petriew and arrive to us.

The following chart shows the distance of Comet 185P/Petriew 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 185P/Petriew from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Comet 185P/Petriew to Earth

Between 1 January 2013 and 30 December 2100, the closest approach of Comet 185P/Petriew to Earth happens on Tue Nov 7 2056 at a distance of 0.281733 Astronomical Units, or 42,146,691 kilometers:

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

Comet 185P/Petriew Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 185P/Petriew, 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.

Visualization of Comet 185P/Petriew Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Comet 185P/Petriew with respect of the Sun and the orbits of the major planets. The position of Comet 185P/Petriew and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System.
