Comet 126P/IRAS

Comet 126P/IRAS is currently in the constellation of Cetus.

The current Right Ascension of Comet 126P/IRAS is 01h 10m 04s and the Declination is -06° 45’ 23” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom edit_location_alt). The current estimated magnitude of Comet 126P/IRAS is 14.44 (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 126P/IRAS Distance from Earth

The distance of Comet 126P/IRAS from Earth is currently 302,764,794 kilometers, equivalent to 2.023858 Astronomical Units. Light takes 16 minutes and 49.9146 seconds to travel from Comet 126P/IRAS and arrive to us.

The following chart shows the distance of Comet 126P/IRAS 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 126P/IRAS from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Comet 126P/IRAS to Earth

Between 1 January 2013 and 30 December 2100, the closest approach of Comet 126P/IRAS to Earth happens on Sun Sep 21 2036 at a distance of 0.789425 Astronomical Units, or 118,096,354 kilometers:

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

Comet 126P/IRAS Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 126P/IRAS, 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 126P/IRAS Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Comet 126P/IRAS with respect of the Sun and the orbits of the major planets. The position of Comet 126P/IRAS 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!
