Comet 242P/Spahr is currently in the constellation of Cetus. The current Right Ascension of Comet 242P/Spahr is 00h 28m 59s and the Declination is -00° 59’ 52” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current estimated magnitude of Comet 242P/Spahr is 18.83 (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.
- 242P/Spahr is below the horizon from Greenwich, United Kingdom .
- Given its current magnitude, 242P/Spahr is visible only through long exposure photography.

Comet 242P/Spahr Distance from Earth
The distance of Comet 242P/Spahr from Earth is currently 516,612,107 kilometers, equivalent to 3.453339 Astronomical Units. Light takes 28 minutes and 43.2325 seconds to travel from Comet 242P/Spahr and arrive to us.
The following chart shows the distance of Comet 242P/Spahr 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 242P/Spahr from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Comet 242P/Spahr to Earth
Between 1 January 2000 and 31 December 2099, the closest approach of Comet 242P/Spahr to Earth happens on Fri Oct 17 2036 at a distance of 3.065836 Astronomical Units, or 458,642,481 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Comet 242P/Spahr Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Comet 242P/Spahr, 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.
