Comet 354P/LINEAR

Comet 354P/LINEAR is currently in the constellation of Aries. The current Right Ascension of Comet 354P/LINEAR is 03h 25m 14s and the Declination is +22° 25’ 17” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet 354P/LINEAR is 21.07 (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 354P/LINEAR Distance from Earth

The distance of Comet 354P/LINEAR from Earth is currently 450,486,641 kilometers, equivalent to 3.011317 Astronomical Units. Light takes 25 minutes and 2.6617 seconds to travel from Comet 354P/LINEAR and arrive to us.

The following chart shows the distance of Comet 354P/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 354P/LINEAR from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Comet 354P/LINEAR to Earth

Between 1 January 2013 and 30 December 2100, the closest approach of Comet 354P/LINEAR to Earth happens on Mon Dec 28 2054 at a distance of 1.023462 Astronomical Units, or 153,107,675 kilometers:

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

Comet 354P/LINEAR Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 354P/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.

Visualization of Comet 354P/LINEAR Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Comet 354P/LINEAR with respect of the Sun and the orbits of the major planets. The position of Comet 354P/LINEAR and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!
