Comet 364P/PANSTARRS is a periodic comet with an orbital period of 4.9 years. It was discovered by the Pan-STARRS survey on February 13, 2013. It has a highly elliptical orbit with a perihelion distance of 0.8 astronomical units (AU) and an aphelion distance of 4.9 AU. The comet is classified as a Jupiter-family comet, meaning its orbit is controlled and highly influenced by Jupiter's gravity. The next perihelion passage happens on May 11, 2023, and the next one after that will happen in April 2028.

Coma Diameter (COBS) n/a

Tail Length (COBS) n/a

Observation Date (COBS) n/a

Predicted Magnitude (JPL) 26.36

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.

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 364P/PANSTARRS from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach

Between 1 January 2000 and 31 December 2099, the closest approach of Comet 364P/PANSTARRS to Earth happens on Sat Apr 8 2023 at a distance of 0.120732 Astronomical Units, or 18,061,227 kilometers:

Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 364P/PANSTARRS, 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.
