Comet 230P/LINEAR

Altitude: 36.1°   Azimuth: 195.9°   Direction: South-South-West

Comet 230P/LINEAR is currently in the constellation of Virgo.

The current Right Ascension of Comet 230P/LINEAR is 14h 34m 36s and the Declination is -01° 17’ 08” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet 230P/LINEAR is 22.42 (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.

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 230P/LINEAR from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Comet 230P/LINEAR to Earth

Between 1 January 2013 and 30 December 2100, the closest approach of Comet 230P/LINEAR to Earth happens on Sat Dec 5 2015 at a distance of 0.547771 Astronomical Units, or 81,945,347 kilometers:

Comet 230P/LINEAR Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 230P/LINEAR, 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.
