Comet 240P/NEAT Distance

The distance of Comet 240P/NEAT from Earth is currently 680,268,242 kilometers, equivalent to 4.547312 Astronomical Units. Light takes 37 minutes and 49.1306 seconds to travel from Comet 240P/NEAT and arrive to us.

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 240P/NEAT from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Comet 240P/NEAT to Earth

Between January 2013 and December 2100 the closest approach of Comet 240P/NEAT to Earth happens on Wed Nov 24 2055 at a distance of 1.12394517 Astronomical Units, or 168,139,805 kilometers:

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

Comet 240P/NEAT brightness

The current visual magnitude of Comet 240P/NEAT is 19.11.


The observed magnitude and coma diameter values are derived from the Comet Observers Database by averaging the values reported in recent observations (more recent than 4 days), when available. The Estimated Magnitude comes from the JPL Horizons ephemerides service and might be inaccurate given the highly dynamic and unpredictable behvior of comets. When available, please refer to the Observed Magnitude value and consider the Estimated 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 following chart is the predicted light curve (visual magnitude as a function of time) of Comet 240P/NEAT, 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.

Comet 240P/NEAT rise and set times

Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London

Today's Comet 240P/NEAT rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 70.3°
Max altitude: 58.2°
Azimuth: 289.6°
Comet 240P/NEAT is above the horizon from Greenwich, United Kingdom

The rise and set times are defined as the time at which the upper limb of Comet 240P/NEAT touches the horizon, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
