Comet 402P/LINEAR is currently in the constellation of Leo. The current Right Ascension of Comet 402P/LINEAR is 11h 44m 33s and the Declination is +21° 46’ 14” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current estimated magnitude of Comet 402P/LINEAR is 20.35 (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.
- 402P/LINEAR is above the horizon from Greenwich, United Kingdom .
- Right now it is placed in the South direction at an altitude of 60° above the horizon.
- Given its current magnitude, 402P/LINEAR is visible only through long exposure photography.

Comet 402P/LINEAR Distance from Earth
The distance of Comet 402P/LINEAR from Earth is currently 922,405,037 kilometers, equivalent to 6.165897 Astronomical Units. Light takes 51 minutes and 16.8120 seconds to travel from Comet 402P/LINEAR and arrive to us.
The following chart shows the distance of Comet 402P/LINEAR 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 402P/LINEAR from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet 402P/LINEAR to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Comet 402P/LINEAR to Earth happens on Tue Dec 28 2021 at a distance of 3.002067 Astronomical Units, or 449,102,869 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 402P/LINEAR Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 402P/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.
